Ready for review. Opened for visibility and tracking against #21940. The scanner's version-extraction path has not been validated against a live VeloCloud Orchestrator instance, so end-to-end version detection is not proven. I will move it out of draft once the version fingerprint is confirmed on a real VCO. Verification Steps below spell out exactly what is and isn't done.
Description
Two detection-only modules for CVE-2026-93952, a critical improper input validation flaw (CWE-20) in on-premises Arista (formerly VMware) VeloCloud Orchestrator (VCO), disclosed 2026-09-22 and reported as actively exploited (added to the CISA KEV catalog). Arista PSIRT scores it CVSS v3.1 10.0 / CVSS v4.0 9.5. Neither module attempts exploitation; this covers detection and compromise-triage only.
auxiliary/scanner/http/velocloud_orchestrator_version confirms the target is a VCO - using the Shodan/nuclei-compatible login-favicon MurmurHash3 (-2062596654) as the authoritative product signal, with a landing-page string match as fallback - then makes a best-effort read of the version, parses it with Rex::Version, and reports whether it falls within a CVE-2026-93952 affected range per release train:
Train
Affected
Fixed
5.2
<= 5.2.3.15
5.2.3.16
6.4
<= 6.4.2.7
6.4.2.8
6.1
<= 6.1.3.7
fix pending
7.0
<= 7.0.0.2
fix pending
The output states that actual exposure also requires certificate-based Edge-to-VCO authentication (Certificate Acquire or Certificate Required mode), which can't be determined by remote version fingerprinting. A "vulnerable" result means "running an affected version," not "confirmed exploitable."
post/linux/gather/velocloud_cve_2026_93952_ioc_check is a read-only forensic check for an operator to run on a VCO host they administer. It looks for the published host-side indicators of compromise: known malicious file artifacts, the MD5 of the vc-sysmond implant, the malicious vc-sysmon.service systemd unit, and the reported attacker IPs in nginx access logs. It reports a vuln and note on any match and is explicit that a clean result is not proof the host is uncompromised.
Both modules ship with documentation pages under documentation/modules/.
None. Two new modules and their docs; nothing existing is modified.
Reviewer Notes
Product detection is implemented; version detection is the open question. The favicon MurmurHash3 (-2062596654, per the ProjectDiscovery favicon-hash template) is the only confirmed unauthenticated fingerprint for the product, and it is now wired in as an additive signal. The hash machinery is validated offline: the MurmurHash3 x86_32 implementation matches the canonical Python mmh3 vectors, and the 76-character base64 wrap reproduces Python base64.encodebytes byte-for-byte (Ruby's Base64.encode64 wraps at 60 and would produce a different value). The signal is additive, so detection still succeeds on either the favicon hash or the string match - an incorrect constant only falls back to string matching, with no regression.
What the favicon hash does not give is the version. Public research (the Arista VeloCloud OpenAPI guide, the vcoclient project, ProjectDiscovery nuclei templates) indicates the VCO REST API under /portal/rest is authenticated, and no public unauthenticated version endpoint is documented, so an unauthenticated version read may not be feasible on every build. That is what the live-instance validation needs to answer, and it is called out in the code comments. The favicon constant itself is nuclei-sourced and, like the version read, still wants confirmation against a real VCO. Feedback from anyone with on-prem VCO access on how the build version is exposed would be welcome.
Scope: the exploitation primitive for CVE-2026-93952 is intentionally out of scope. The vendor advisory withholds the mechanics, two release trains remain unpatched, and the flaw is under active exploitation. This is detection and triage only.
Verification Steps
bundle exec rspec on both specs -> 37 examples, 0 failures.
rubocop clean on both modules and both specs.
msftidy clean on both modules.
Pending, and the reason this is a draft: get_version (and the favicon constant) validated against a live VCO instance. The version-range comparison and the hash machinery are spec-verified; the values they compare against (the build-version signal and the favicon hash) are best guesses until confirmed on a real orchestrator.
Test Evidence
$ bundle exec rspec spec/modules/auxiliary/scanner/http/velocloud_orchestrator_version_spec.rb \
spec/modules/post/linux/gather/velocloud_cve_2026_93952_ioc_check_spec.rb
37 examples, 0 failures
$ bundle exec rubocop <both modules and both specs>
4 files inspected, no offenses detected
$ ruby tools/dev/msftidy.rb <each module>
1 file inspected, no offenses detected
The scanner spec locks the version boundaries in the table above and adds MurmurHash3 known-answer vectors plus a favicon fixture whose 76-character wrap changes the hash (guarding both the hash and the encoding); the post-module spec exercises each detection path plus the clean and compromised run outcomes with a stubbed session.
Summary by CodeRabbit
Summary by CodeRabbit
New Features
Added a VeloCloud Orchestrator scanner that identifies instances and checks readable versions against affected releases for CVE-2026-93952. A version-based finding alone does not confirm exposure.
Added a read-only host check for published CVE-2026-93952 indicators. Matches are reported for review; no matches do not prove a host is uncompromised.
Documentation
Added setup and verification instructions, scanner options, indicator details, and example results for both checks.
Detection-only auxiliary scanner that fingerprints the Arista (formerly
VMware) VeloCloud Orchestrator web interface and reports whether the
detected version falls within a range affected by CVE-2026-93952
(CVSS 10.0, CWE-20). Makes no attempt to exploit the flaw.
Note: actual exposure also requires certificate-based Edge-to-VCO
authentication, which cannot be determined by remote version
fingerprinting; the module output states this. The version-extraction
path still needs validation against a live VCO instance.
Refs: rapid7#21940
Read-only Linux post module that checks a VeloCloud Orchestrator host for
the published host-side indicators of compromise associated with
CVE-2026-93952 exploitation: known malicious file artifacts, the MD5 of
the vc-sysmond implant, the malicious systemd unit, and the reported
attacker IPs in nginx access logs. Defensive/forensic only; no
exploitation. Companion to the version scanner.
Refs: rapid7#21940
Rex::Version#version returns the version string, not its segments, so the
train key was derived from String#take (which does not exist) and would
raise NoMethodError at runtime. Use #segments to build the major.minor
train key.
Scanner spec locks the CVE-2026-93952 affected/fixed version boundaries
per release train. IOC post-module spec exercises each detection path
(files, implant MD5, systemd unit, attacker IPs in nginx logs) and the
clean/compromised run outcomes with a stubbed session.
Public research (Arista OpenAPI guide, vcoclient, nuclei templates) shows
the VCO REST API under /portal/rest is authenticated and the only confirmed
unauthenticated fingerprint is a favicon MurmurHash3 that identifies the
product but not its version. Record this in get_version and looks_like_vco?
so the version-extraction path is understood to be a best guess pending
validation against a live instance, not a solved problem.
Wire the Shodan/nuclei-compatible favicon MurmurHash3 (mmh3 -2062596654)
into the VeloCloud Orchestrator scanner as an additive product-identification
signal alongside the existing landing-page string match. The favicon is the
only confirmed unauthenticated fingerprint for the product.
mmh3_x86_32 is a MurmurHash3 x86_32 (seed 0, signed) implementation matching
the Python mmh3 convention. favicon_mmh3 encodes the favicon with a 76-char
base64 wrap and trailing newline to match Python base64.encodebytes, which is
what Shodan and the nuclei templates hash (Ruby's Base64.encode64 wraps at 60
and would produce a different value).
The signal is additive: detection still succeeds on either the favicon hash or
the string match, so an incorrect favicon constant only falls back to string
matching with no regression.
Specs add canonical mmh3 known-answer vectors and a favicon fixture whose
76-char wrap changes the hash, guarding both the hash and the encoding.
Add the missing documentation pages for the VeloCloud Orchestrator version
scanner and the CVE-2026-93952 IOC compromise-check post module, covering the
affected release trains, the certificate-mode exposure caveat, options, and
console scenarios.
…ries
NVD records two Arista PSIRT scores for CVE-2026-93952: CVSS v3.1 10.0 and
CVSS v4.0 9.5 (the v4 Attack Complexity is High). State both instead of the
bare 'CVSS 10.0', which cited only the v3.1 base.
Replace the news-article reference with the Arista security advisory
(24765-security-advisory-0183) and the CISA Known Exploited Vulnerabilities
catalog entry as the authoritative primary sources.
Cite the ProjectDiscovery favicon-detect template that maps -2062596654 to
arista-velocloud via mmh3(base64_py(body)), the exact expression favicon_mmh3
reproduces, and note the same Shodan dork used in public SD-WAN census research.
Records that the constant is corroborated by two independent sources but not yet
re-hashed against a live appliance.
On the current Arista-era VCO builds the SPA router intercepts
/favicon.ico and returns the 750-byte landing HTML, so the original
favicon_mmh3 hashed the wrong bytes and never matched -2062596654. The
actual favicon lives at /apps/root/favicon.ico and hashes to the
expected value under both the module's Ruby mmh3_x86_32 and the
reference Python mmh3 library, verified against two live hosted
Orchestrators (vco1-usvi1 and vco996-usvi1.velocloud.net, 2026-11-08).
- favicon_mmh3 now accepts a path argument.
- favicon_match? tries /apps/root/favicon.ico first and falls back to
/favicon.ico so older VMware-era builds keep working.
- login_cookie_match? adds a last-resort product signal from the
velocloud.* Set-Cookie headers on /login/, invoked only when both
favicon and body checks miss so most hosts cost no extra request.
- Specs cover the new path argument, multi-path favicon_match?, the
Angular SPA fixture for looks_like_vco?, and login_cookie_match?.
Replaces the pre-draft hedge about the unauthenticated version endpoint
with a Live-instance validation section that names the exact endpoints
checked (favicon, landing HTML, /login/, /portal/*, module federation
manifest, SPA source maps, response headers), what each returned, and
what that means for get_version on current builds. Also records that
-2062596654 was reproduced on live hosts and updates the detection
summary to mention the Set-Cookie fallback.
The pull request adds an HTTP scanner that identifies VeloCloud Orchestrator and assesses readable versions for CVE-2026-93952. It also adds a Linux/Unix post module that checks hosts for published indicators. Documentation and specs cover both modules.

Did the passive live test the draft was blocked on. Three new commits reflect what the orchestrator actually does, and the module is now ready for a first look.
Confirmed against two Arista-hosted VCOs (vco1-usvi1 and vco996-usvi1.velocloud.net, SPA Last-Modified: 2026-10-22):
-2062596654 is the right constant, but it hashes /apps/root/favicon.ico (1406-byte ICO), not /favicon.ico. The Angular SPA router intercepts /favicon.ico and returns the 750-byte landing HTML, which hashes to something else entirely, so the old favicon branch was effectively dead code on current builds.
Cross-verified: both the module's own Ruby mmh3_x86_32 and the reference Python mmh3.hash(base64.encodebytes(bytes)) produce -2062596654 on the bytes fetched from either host.
Landing HTML references @velocloud/vco-header, which keeps the looks_like_vco? fallback firing via the lowercase velocloud substring.
/login/ sets velocloud.session / velocloud.csrf / velocloud.message cookies, now wired as a last-resort product signal via login_cookie_match?. Only invoked when both favicon and body checks miss, so no extra request on the happy path.
Version-endpoint question, with evidence instead of a hedge:
Path
Result
GET /portal/
404
GET /portal/rest/
404
GET /portal/rest/login/enterpriseLogin
404
GET /apps/root/assets/module-federation.manifest.json
{} (microfrontends load post-auth)
GET /apps/root/main.js and its source map
No build / version string
Response headers
Server and X-*-Version stripped
GET /login/ body
302 to / plus cookie clears
No unauthenticated version endpoint on these builds. get_version returns nil and the module cleanly falls back to product-detection output ("detected, but version could not be determined"). Kept the best-effort SPA-bundle / landing-page regexes in place so (a) older VMware-era builds that do leak a version string still get a Vulnerable / Not vulnerable verdict, and (b) if a future build re-exposes the string at /portal/, the code path is already there. The honest wording lives in the module doc and the get_version comment.
What changed
modules/auxiliary/scanner/http/velocloud_orchestrator_version.rb: favicon_mmh3 takes a path, favicon_match? tries /apps/root/favicon.ico first with /favicon.ico as a fallback, login_cookie_match? added as a last-resort product signal, comments updated with live-test provenance.
spec/modules/auxiliary/scanner/http/velocloud_orchestrator_version_spec.rb: locked in the path argument, the multi-path favicon_match? behavior, an Angular-SPA fixture for looks_like_vco?, and login_cookie_match? responses.
documentation/modules/auxiliary/scanner/http/velocloud_orchestrator_version.md: added a Live-instance validation section documenting the actual endpoints and what each returned.
bundle exec rspec: bundle-exec boot is slow on my dev machine and did not complete locally within the time budget; leaning on CI here. The spec's existing stubs (send_request_cgi, instance_double(Rex::Proto::Http::Response, ...)) match the patterns already in the file and in other scanner specs, so the new examples follow the same shape. If anything catches, happy to push a fix in response to CI output.

Do not swallow probe errors silently as "not present".
When file? raises, safe_file? returns false. The run then reports a clean result even when probes failed. This is a false negative for a forensic check. Track probe failures and warn the operator that the result is incomplete. Also use elog to keep the exception details.

Update safe_file? so a file? exception is not treated as a clean negative:
record the probe failure and warn the operator that the forensic result may be
incomplete. Log the exception details with elog, and preserve the false return
so existing probe flow remains unchanged.

report_note previously fired only after get_version returned a build
string, so a successful product detection on a build that does not
expose a version (the current Arista-hosted builds; see the module
doc) never made it into the services table. Add a report_service call
right after the detection signal resolves so the host still shows up
for inventory and follow-up regardless of version readability.
…signalling
Addresses correctness gaps surfaced by review and closes one IOC gap
against the Arista advisory.
- Match attacker IPs against nginx's client-address field with a
grep -E '^<ip>[[:space:]]' pattern. Previously a request for
/142.93.149.77 would false-positive via grep -F against the whole
line and record a clean host as compromised.
- Add the attacker-request header x-vc-opt as an IOC; the advisory
lists it alongside the IPs but the module previously only scanned
for IPs. Matched case-insensitively and bounded (-F -i -m1) over the
same nginx log paths.
- Report IOC matches as a note instead of a vulnerability. An IOC is
evidence of past attacker activity, not proof the host is
vulnerable to CVE-2026-93952 (patched hosts can have attacker
artifacts; compromised hosts can already be patched). Aligns with
the Arista advisory's own "no single definitive indicator" wording.
- Warn when the MD5 digest cannot be computed on a file that exists,
so a hash that silently fails is not mistaken for a clean result.
- Count probe failures in safe_file? and MD5 compute failures, and
print a "probe(s) failed; this result is incomplete" warning at the
end of the run so a forensic clean bill of health is never issued
on an incomplete scan. Also use elog for the exception details.
- Spec: exercise the anchored IP path, the header IOC, the no-vuln
invariant, and the partial-result warning.
- Doc: add x-vc-opt to the indicator table, note the anchored-field
behavior, and update the reporting language from vulnerability to
note.
@coderabbitai - all five actionable findings landed in c874c346 + b561f88e, and the x-vc-opt IOC gap vs. the Arista advisory is closed in the same pass.
Scanner (c874c346)
Added report_service right after the detection signal resolves, so a VCO on a current Arista build (where get_version returns nil) still shows up in the services table.
Post module (b561f88e)
check_logs now anchors each attacker IP to nginx's client-address field with grep -E '^<ip>[[:space:]]', so a request path containing /142.93.149.77 no longer false-positives. New spec case locks this in.
Added x-vc-opt as a header IOC (the Arista advisory lists it alongside the IPs; the module was only scanning IPs). Case-insensitive, bounded, over the same nginx log paths.
Replaced report_vuln with report_note on IOC matches. IOCs are evidence of past attacker activity, not a proof the host is currently vulnerable to CVE-2026-93952 - this matches the advisory's own "no single definitive indicator" wording. Spec now asserts report_vuln is not called.
check_hashes now warns when MD5 can't be computed on an existing file and counts the failure.
safe_file? now counts probe failures and uses elog for exception detail. warn_on_partial_result prints a visible "N probe(s) failed; this result is incomplete" at the end of the run, so a forensic clean bill of health is never issued on an incomplete scan.
Doc updated: added x-vc-opt to the indicator table, noted the anchored-field match, and switched the reporting language from "vulnerability" to "note".
Local checks: bundle exec rubocop - 4 files inspected, no offenses. ruby -c - syntax OK on all four. rspec is still slow to boot on my machine; leaning on CI.

Both arrays are empty. The repository rule says to resolve empty Notes arrays before submitting. The module runs grep and md5sum through the session. These commands can appear in shell history and audit logs. Declare SideEffects as [ IOC_IN_LOGS ]. For Reliability, use [] only if you can justify it. Otherwise, choose a suitable value.

@Pushpenderrathore Thanks for the updates. I confirmed that the scanner records the service and that the IOC module reports matches as a note.
Three issues remain at b561f88e:
CI is failing. The Ruby 3.4 RSpec job fails at spec/modules/post/linux/gather/velocloud_cve_2026_93952_ioc_check_spec.rb Line 65. The stub expects an unescaped IP, but check_logs uses Regexp.escape, so the stub returns an empty result. Four other non-content RSpec jobs were cancelled. The request-path negative test also returns an empty string unconditionally, so it does not verify the generated pattern against that path.
A failed MD5 probe can still be silent. For Meterpreter, file_remote_digestmd5 can catch an exception and return nil. check_hashes skips that result without incrementing @probe_errors, so the final result is not marked incomplete.
The header check can match unrelated log fields. The x-vc-opt grep scans the whole line. A request path containing that text can therefore produce a header IOC. Please restrict the match to a supported header field or format and add a negative case.
Please fix these cases and rerun the affected specs and CI. Per the retained repository review guidance, please also share command output for the post module’s indicator and incomplete-scan cases; those runtime results remain unverified.

If you found this review helpful, would you consider giving us a shout-out on X?
@Pushpenderrathore Thanks for the updates. At b561f88e, I confirmed that the scanner records the detected service and that the post module records IOC findings as a note.
Three issues from the earlier reply remain:
RSpec fails in CI. The Ruby 3.4 job fails because the IP stub does not account for Regexp.escape. The request-path negative test also returns an empty result without testing the generated pattern. Other non-content RSpec jobs were cancelled.
A failed MD5 probe may not mark the scan incomplete.file_remote_digestmd5 can return nil after an error, but check_hashes skips that result without incrementing @probe_errors.
The header check can match a request path. The x-vc-opt search covers the whole log line. Please restrict it to a supported header-log format and add a negative test.
Please fix these issues and rerun the affected specs and CI before merging. Per the repository’s review guidance, please also share the commands and observed post-module output for an IOC match and a failed probe. Those runtime results remain unverified.

## Testing
- Derive output expectations from real captures rather than assumptions. Prefer stable structural/anchored matches and include meaningful negative cases.
… doc scenarios
- Fill in the empty Reliability Notes array with REPEATABLE_SESSION.
The module makes read-only GET requests and produces the same result
on repeat runs against a stable host, which matches that marker; the
repo guidelines require a non-empty Reliability note on auxiliary
modules.
- Use proto: 'tcp' on report_note so the version note attaches to the
service recorded by report_service, which keys records by transport
protocol. The previous 'http' / 'https' value was the application
protocol and could leave the note orphaned.
- Replace the fabricated "Affected version detected" scenario output
with real console output captured from the 2026-11-08 run against
vco996-usvi1.velocloud.net, and relabel the version-detected example
as illustrative (no current build in the public space leaks a
version string, so that output cannot be captured at this time).
- Add a readable_log? probe (test -r) before running the IOC greps in
check_logs. A log the session user cannot read made every grep
return empty output, so the previous code silently registered
"no hit" and warn_on_partial_result stayed quiet; the result was a
forensic clean bill of health on a host whose logs we could not
actually see. Unreadable logs now print a warning, increment
@probe_errors, and skip IOC greps on that file.
- Fix the check_logs client-address-field spec: the Regexp.escape call
in the IP match emits backslash-escaped dots, so the previous stub
checking start_with?("grep -E -m1 '^142.93.149.77") never matched
the actual cmd and the test failed in CI. Rewrite the stub helper
to match against Regexp.escape(ip) and compose per-test grep
behavior through a shared stub_readable_log_with block. Add a case
covering the new readable_log? gate.
The only failing CI job was my own check_logs spec: Regexp.escape(ip) emits 142\.93\.149\.77 in the grep command, and the previous stub's start_with?("grep -E -m1 '^142.93.149.77") therefore never matched. Rewrote the stub helper to key off Regexp.escape(ip) and composed the per-test grep behavior through a stub_readable_log_with block. Added a case for the new readable_log? gate.
New CodeRabbit findings - all four landed:
Reliability note: filled in with REPEATABLE_SESSION. The scanner makes read-only GETs and produces the same result on repeat runs against a stable host, which matches that marker.
report_note proto: changed from ssl ? 'https' : 'http' to 'tcp'. Service records key by transport protocol, so the previous value could leave the note orphaned from the service reported alongside it.
Doc scenarios: replaced the fabricated "Affected version detected" output with real console output captured from the 2026-11-08 run against vco996-usvi1.velocloud.net, and relabeled the version-detected example as illustrative. No current public build leaks a version string, so that specific output cannot be captured right now; the doc now says so.
check_logs unreadable-log gap: added a readable_log? probe (test -r) before running the IOC greps. A log the session user cannot read used to return empty from every grep and silently register as "no hit"; warn_on_partial_result therefore stayed quiet on hosts whose logs we could not actually see. Unreadable logs now print a warning, increment @probe_errors, and skip the IOC greps on that file, which matches what the module doc already promised.
Local checks: bundle exec rubocop on all four files - no offenses. ruby -c - syntax OK on all four. Leaning on CI for rspec.

@Pushpenderrathore Thanks for the fixes. At 1c532f70, I confirmed that the scanner records the service without a version and the post module records IOC matches as a note. The unreadable-log probe and escaped-IP stub are also present.
Three findings remain:
check_hashes skips a nil MD5 result. A helper error can therefore leave the scan marked complete.
The x-vc-opt search covers the whole log line. A request path containing that text can produce a false header match.
The attacker-IP negative test returns an empty result without testing the generated grep pattern.
Please fix these cases and rerun the affected specs. When I checked, 18 CI jobs had passed and the Ruby 3.2 non-content RSpec job was still running. Please confirm that it passes after the fixes.
The repository’s review guidance also requires runtime evidence. Please share the commands and observed output from an authorized test host for an IOC match and a failed probe. Include the recorded IOC note and the incomplete-result warning. Live version detection also remains unverified on a host that exposes a version.

### Console Output
- Tcp and scanner mixins prepend host:port through `print_prefix`; do not duplicate `#{peer}`, `#{rhost}:#{rport}`, or authority strings in messages. `Lint/RedundantPeerInPrint` is syntactic and may false-positive on HttpClient-only modules.

## Module Development
### Output and Reporting
- Call `report_vuln` when a vulnerability can be reported
Previously login_cookie_match? stringified the entire response header
block and matched the substring "velocloud." anywhere in it. A
vendor-branded Server line (or any other non-cookie header value) that
happens to contain that substring would misidentify an unrelated
service as a VeloCloud Orchestrator. The scan now iterates the
headers.to_s one line at a time and matches only headers that start
with "Set-Cookie:" followed by a value beginning with "velocloud.",
which is how VCO actually emits velocloud.session, velocloud.csrf and
velocloud.message on /login/.
Spec: switch the Headers fixture from a bare Hash to an instance_double
whose to_s returns a real raw header block, since the implementation
now inspects the HTTP-formatted header text. Add a negative case
covering a non-cookie header whose value contains "velocloud." so the
regression that motivated the change stays locked in.
…red-pattern test
- check_hashes: treat a nil MD5 return from file_remote_digestmd5 as a
probe failure regardless of whether the helper raised. Some
Meterpreter wrappers catch internal exceptions and return nil, so the
previous `rescue + next if actual.nil?` could silently skip without
incrementing @probe_errors and let the run be reported as complete
when the hash was never computed.
- check_logs header grep: narrow from a whole-line fixed-string match
to a regex that requires a header-syntax position
(`([[:space:]"])x-vc-opt[[:space:]]*[":=]`). A request path like
GET /x-vc-opt in nginx's quoted request field is preceded by '/'
and would no longer match. The header is still caught in common
log formats where the name is logged with a `:` or `=` delimiter.
- Spec: replace the tautological "does not flag a path" test with a
case that captures each generated cmd and asserts the IP grep
pattern actually anchors to the client-address field. Add a positive
case for the new header regex, a negative case that verifies the
generated header pattern requires boundary characters, and a case
for the new silent-nil digest handling in check_hashes.
check_hashes: a nil MD5 return (no raise) now counts as a probe failure, so warn_on_partial_result fires.
x-vc-opt grep narrowed to a header-syntax position: ([[:space:]"])x-vc-opt[[:space:]]*[":=]. Request paths like /x-vc-opt no longer match.
Attacker-IP negative test now captures each cmd and asserts the pattern anchors with ^<ip>[[:space:]], not just that an empty stub returns [].
login_cookie_match? matches only Set-Cookie: velocloud. lines, not any whole-header substring.
Runtime evidence: no public build in the Shodan/crt.sh cohort currently leaks a version, so the "version detected" scenario can't be captured here (documented in the Live-instance validation section). Happy to run against a lab target if a reviewer has one.

@Pushpenderrathore Thanks for the fixes and for explaining the lab limits. I understand you are waiting for human review.
At cbd20a3a, I confirmed the nil-MD5 handling, anchored IP test, and cookie-header restriction are present. Two items need attention before merge:
CI is failing on the current head. Three cookie specs fail because Rex::Proto::Http::Headers is uninitialized at spec/modules/auxiliary/scanner/http/velocloud_orchestrator_version_spec.rb Line 159. Please correct the fixture and rerun the specs and cancelled CI jobs. The separate Ruby 3.3 setup job failed with HTTP 504 and should also be retried. RSpec job
The x-vc-opt search still scans the whole log line. It can match "x-vc-opt" in another quoted field. A log format that records only $http_x_vc_opt also records the value, not necessarily the header name. Please validate the match against a supported VCO log format.
Per the repository’s review guidance, an authorized lab is still needed to capture an IOC note and an incomplete-scan warning. Version detection on a host that exposes a version also remains unverified. A human reviewer can help arrange that validation.

If a non-root shell cannot traverse a log’s parent directory, file? returns false. The module then skips the log without warning, so it can miss indicators and report no matches. Meterpreter stat errors are also converted to false by file?, before safe_file? can catch them.
Distinguish inaccessible paths from absent paths and mark the scan incomplete when access is denied.

Ready for review. Opened for visibility and tracking against #21940. The scanner's version-extraction path has not been validated against a live VeloCloud Orchestrator instance, so end-to-end version detection is not proven. I will move it out of draft once the version fingerprint is confirmed on a real VCO. Verification Steps below spell out exactly what is and isn't done.
Description
Two detection-only modules for CVE-2026-93952, a critical improper input validation flaw (CWE-20) in on-premises Arista (formerly VMware) VeloCloud Orchestrator (VCO), disclosed 2026-09-22 and reported as actively exploited (added to the CISA KEV catalog). Arista PSIRT scores it CVSS v3.1 10.0 / CVSS v4.0 9.5. Neither module attempts exploitation; this covers detection and compromise-triage only.
auxiliary/scanner/http/velocloud_orchestrator_versionconfirms the target is a VCO - using the Shodan/nuclei-compatible login-favicon MurmurHash3 (-2062596654) as the authoritative product signal, with a landing-page string match as fallback - then makes a best-effort read of the version, parses it withRex::Version, and reports whether it falls within a CVE-2026-93952 affected range per release train:<= 5.2.3.155.2.3.16<= 6.4.2.76.4.2.8<= 6.1.3.7<= 7.0.0.2The output states that actual exposure also requires certificate-based Edge-to-VCO authentication (Certificate Acquire or Certificate Required mode), which can't be determined by remote version fingerprinting. A "vulnerable" result means "running an affected version," not "confirmed exploitable."
post/linux/gather/velocloud_cve_2026_93952_ioc_checkis a read-only forensic check for an operator to run on a VCO host they administer. It looks for the published host-side indicators of compromise: known malicious file artifacts, the MD5 of thevc-sysmondimplant, the maliciousvc-sysmon.servicesystemd unit, and the reported attacker IPs in nginx access logs. It reports a vuln and note on any match and is explicit that a clean result is not proof the host is uncompromised.Both modules ship with documentation pages under
documentation/modules/.Related Issue: tracking issue #21940
Breaking Changes
None. Two new modules and their docs; nothing existing is modified.
Reviewer Notes
Product detection is implemented; version detection is the open question. The favicon MurmurHash3 (
-2062596654, per the ProjectDiscovery favicon-hash template) is the only confirmed unauthenticated fingerprint for the product, and it is now wired in as an additive signal. The hash machinery is validated offline: the MurmurHash3 x86_32 implementation matches the canonical Pythonmmh3vectors, and the 76-character base64 wrap reproduces Pythonbase64.encodebytesbyte-for-byte (Ruby'sBase64.encode64wraps at 60 and would produce a different value). The signal is additive, so detection still succeeds on either the favicon hash or the string match - an incorrect constant only falls back to string matching, with no regression.What the favicon hash does not give is the version. Public research (the Arista VeloCloud OpenAPI guide, the vcoclient project, ProjectDiscovery nuclei templates) indicates the VCO REST API under
/portal/restis authenticated, and no public unauthenticated version endpoint is documented, so an unauthenticated version read may not be feasible on every build. That is what the live-instance validation needs to answer, and it is called out in the code comments. The favicon constant itself is nuclei-sourced and, like the version read, still wants confirmation against a real VCO. Feedback from anyone with on-prem VCO access on how the build version is exposed would be welcome.Scope: the exploitation primitive for CVE-2026-93952 is intentionally out of scope. The vendor advisory withholds the mechanics, two release trains remain unpatched, and the flaw is under active exploitation. This is detection and triage only.
Verification Steps
bundle exec rspecon both specs -> 37 examples, 0 failures.get_version(and the favicon constant) validated against a live VCO instance. The version-range comparison and the hash machinery are spec-verified; the values they compare against (the build-version signal and the favicon hash) are best guesses until confirmed on a real orchestrator.Test Evidence
The scanner spec locks the version boundaries in the table above and adds MurmurHash3 known-answer vectors plus a favicon fixture whose 76-character wrap changes the hash (guarding both the hash and the encoding); the post-module spec exercises each detection path plus the clean and compromised run outcomes with a stubbed session.
