LAB-5060: Improve Oracle ORDS version detection on modern ORDS (24.x/26.x) - #422
Conversation
Modern ORDS emits no Server, X-ORDS-*, X-APEX-* or X-Powered-By header, so the Server-token version parser leaves version empty on current deployments and the CPE degrades to the "any" wildcard, defeating CVE/KEV matching. Add two best-effort version sources, both of which degrade gracefully: - ORDS: the Database Actions / SQL Developer Web client config at /ords/_sdw/js/config.js carries "productName":"SQL Developer","productVersion":"<ver>". It is plain static content from the ORDS distribution and is not covered by any ORDS privilege pattern (oracle.dbtools.sdw.user guards only /_sdw/_services/*), so it reads anonymously wherever a database pool is configured. Only <major>.<minor> is reported: SQL Developer Web pins the patch component at zero for the whole release train (ORDS 26.2.3 ships "26.2.0"), and asserting a patch level the response does not prove would produce false CVE matches. The probe is gated on ORDS already being detected with no Server-header version, so non-ORDS hosts are never sent the extra request. - APEX: the version carried in APEX-rendered markup, via an "?v=" parameter on an /i/ asset, a versioned /i/<ver>/ images directory, or the Oracle CDN images directory. It now populates the application_express CPE, which previously always used the wildcard. It is only read from bodies that already qualified as APEX evidence. Documents in the plugin why nothing better exists: measured against a live ORDS 26.2.3 standalone instance, every anonymous surface (/ords/_/landing and its CSS/JS, /ords/_/lib/*, /ords/_/jet/*, /ords/sign-in/, the problem+json error bodies) is free of any version string. ORDS does return a build-wide ETag on /ords/_/ static resources that identifies a build exactly, but Oracle publishes only ords-latest.zip, so an ETag-to-version table could neither be built nor kept current; that approach is deliberately not attempted. evaluateORDS/detectORDS now return an ordsResult struct rather than four positional values, since the evaluation grew two more outputs. Adds testdata/oracleords/ mock container (modern / modern-noapex / protected / legacy modes) modelled on the live ORDS 26.2.3 responses and the config.js it ships.

Codex Review
Critical Issues
pkg/plugins/services/oracleords/oracleords.go:380infers only a release train such as26.2, butpkg/plugins/services/oracleords/oracleords.go:390andpkg/plugins/services/oracleords/oracleords.go:432publish it as an exact CPE/service version. For an observed ORDS26.2.3, this produces the nonexistent exact version26.2, which can miss patch-specific vulnerability matches. Preserve the train separately and leave the CPE version wildcarded unless the exact patch is known.
Security
No security concerns flagged.
Suggestions
- Add an end-to-end assertion for the new
modern-noapexfixture. Its landing page containsfont-apex(testdata/oracleords/server.go:155), whichbodyHasAPEXtreats as APEX and therefore incorrectly emits an Application Express CPE atpkg/plugins/services/oracleords/oracleords.go:330.

Gemini Review
Critical Issues
None. The implementation handles version extraction safely without introducing risky regex patterns (no catastrophic backtracking paths) or unbounded memory allocations (body reads remain bounded by maxResponseSize).
Security
No security concerns flagged. Information disclosure via unauthenticated client configs (/ords/_sdw/js/config.js) is leveraged correctly for detection without incorrectly flagging the core service itself as anonymously accessible.
Suggestions
- Optimize redundant APEX version parsing: In
evaluateORDS, a response that carries both APEX headers and APEX body markers (like/i/orf?p=) will causeparseAPEXVersion(and its regex evaluations) to run twice on the same up-to-10MB body if the first call doesn't yield a version. You can combine these checks to avoid the redundant parsing:isAPEXBody := strings.HasPrefix(ev.path, "/ords") && bodyHasAPEX(ev.body) if ev.hasAPEXHeader || isAPEXBody { res.apex = true if res.apexVersion == "" { if v := parseAPEXVersion(ev.body); v != "" { res.apexVersion = v } } }

Claude Review Critical issues
Security Test coverage |
Review of #422 caught a regression this PR introduced: parseAPEXVersion ran on any body bodyHasAPEX accepted, and that predicate matches a bare "apex" substring or a bare "/i/" path. Before this PR that only produced a benign apex:true flag; with the new version extraction, a body carrying an unrelated versioned asset such as "/i/2.0/app.js" would stamp application_express:2.0 onto the CPE, turning a flag false positive into a false versioned CVE match. Split the two concerns: - bodyHasAPEX is unchanged and remains the ORDS-DETECTION marker. It must stay broad: modern ORDS emits no Server header, so on those instances matching the landing page's own "apex" strings is the only thing that identifies the service at all. - bodyHasAPEXProduct is new and gates the APEX flag, the application_express CPE and the APEX version. It is an allowlist (f?p=, wwv_flow, the APEX library/UI asset paths, the APEX CDN prefix, apex.jQuery), matched case-insensitively. An allowlist is required rather than a denylist of weak markers. Verified against the live ORDS 26.2.3 instance: its landing page renders an APEX launcher card on every deployment -- disabled when APEX is absent -- so an APEX-free instance still serves fifteen "apex" occurrences (cards__apex_card, card_title_apex, apex-submit-form, apexhelpbutton, ...) on top of the two from the font-apex icon stylesheet. Stripping font-apex alone was tried first and still reported apex:true. Live re-validation against that instance, which has no APEX installed: before cpes:[rest_data_services:*, application_express:*] apex:true after cpes:[rest_data_services:26.2] apex:false This also removes the pre-existing false positive noted in the PR description, and folds the two APEX branches into one so parseAPEXVersion no longer runs twice over a body that can be up to maxResponseSize. Also fixes the failing gosec check: testdata/oracleords/server.go was missing ReadHeaderTimeout (G112), which every other testdata server sets, and its landing page now reproduces the launcher card so the modern-noapex mode actually exercises the false positive it exists to guard against.

Second review round on #422 found a residual of the same bug class the first round fixed. Gating WHERE the version may be read was not enough; the version regex itself was still free to match the wrong asset once the gate opened. On a genuine APEX page -- f?p= present, so bodyHasAPEXProduct legitimately opens -- that also serves an unrelated versioned asset sharing the "/i/" prefix and carries no APEX "?v=" parameter anywhere, parseAPEXVersion matched that unrelated asset: <a href="f?p=4550:1">Sign In</a><script src="/i/2.0/app.js"></script> before apex_version:"2.0" cpes:[..., application_express:2.0] after (no version) cpes:[..., application_express:*] Both "/i/" patterns are now anchored to a directory that actually exists in an APEX images directory (app_ui, apex_ui, libraries, themes). "/i/" on its own is only a convention -- it is APEX's default images prefix, not a reserved path -- so it cannot establish that an asset belongs to APEX. APEX itself is still flagged in that case, because f?p= is genuine evidence; only the unreadable version is dropped. All four testdata modes still resolve 24.1.5, so the tightening costs no real coverage. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Answering the open question: how Chariot actually matches CPEsI left this open as "flagging for the human reviewer" — it's answerable, so I went and read Guard does no CPE version matching for CVEs at all — neither exact nor range. So both "critical" framings of this, Codex's and my counter-argument, were wrong. Evidence: 1. The technology CPE's only NVD call is a display-name lookup, and it deliberately discards the version. func (p *LocalProcessor) processTechnology(technology model.Technology) error {
name, _ := caches.GetCPEHumanNameFromNVD(technology.SearchQuery())
technology.Name = nameand func (c *CPE) SearchQuery() string {
// HACK: Setting version to - (or NA in NVD terms) should match to CPE without a version
// for the technology, which will have JUST a product name in title and no version, etc.
return fmt.Sprintf("cpe:2.3:%s:%s:%s:-", c.Part, c.Vendor, c.Product)
}
2. Every technology lookup is exact-key. 3. The threat pipeline never touches CPEs. 4. No range logic exists. No What this means for the

The first apexVersionPatterns regex captures the ?v= version but has no trailing boundary, so ?v=24.1.5abc silently truncates to "24.1.5". The other two patterns at lines 184-185 already require a trailing /.
Recommend appending a boundary assertion like ["'\s>] after the capture group.

Good catch — fixed in 41ac886. This one was a silent-corruption bug, which is the worst kind here: ?v=24.1.5abc reported 24.1.5, a version the response never stated.
RE2 has no lookahead, so I couldn't assert "not followed by a version character" directly. Went with your suggestion as an explicit terminator alternation, widened slightly to cover the other characters that legitimately end an asset URL, plus end-of-body:
…\?v=(\d+\.\d+(?:\.\d+){0,3})(?:["'\s>&<)]|$)
& and ) are there for ?v=24.1.5&cb=9 and CSS url(…?v=24.1.5); $ so a body that ends on the URL still matches. Verified each form standalone before committing:
"" ← /i/libraries/apex/minified/desktop.min.js?v=24.1.5abc
"" ← /i/libraries/apex/x.js?v=24.1.5.6.7.8
"24.1.5" ← …desktop.min.js?v=24.1.5"
"24.1.5" ← …x.js?v=24.1.5&cb=9
"24.1.5" ← url(/i/themes/theme_42/css/Core.min.css?v=24.1.5)
"24.1.5" ← /i/libraries/apex/x.js?v=24.1.5 (end of body)
All five are now cases in TestParseAPEXVersion (18 subtests).

There was a problem hiding this comment.
When ev.hasAPEXHeader is true (line 396), parseAPEXVersion(ev.body) runs at line 399 against an ungated body; the apexBody variable which carries the bodyHasAPEXProduct guarantee isn't checked. A genuine APEX response with a version-mismatched /i/9.9.9/themes/.../x.css stamps a wrong version onto the CPE.
Recommend adding "&& apexBody" to the inner guard at line 398.
There was a problem hiding this comment.
You're right, and this one is my own inconsistency rather than an oversight — fixed in 41ac886 with exactly the && apexBody you suggested.
The file's doc comment already claims the invariant:
The version is read from that same qualifying body, once
…and then the code didn't honour it on the header path. An X-APEX-* header proves the service is APEX; it says nothing about the body it happened to arrive with. So the guard now reads:
if ev.hasAPEXHeader || apexBody {
res.apex = true
if apexBody && res.apexVersion == "" {
…
}
}res.apex deliberately stays outside the gate — a header-only response is still genuinely APEX, it just has no attributable version. That's the same "prefer no version over a wrong one" line the rest of this PR takes.
Your scenario is now a regression test that fails without the gate:
{
name: "APEX header does not take a version from a non-qualifying body",
evidence: []ordsEvidence{
{path: "/", statusCode: http.StatusOK, hasAPEXHeader: true,
body: `<link rel="stylesheet" href="/i/9.9.9/themes/theme_42/css/Core.min.css">`},
},
expectedAPEX: true, expectedAPEXVersion: "",
},Before the fix it reported 9.9.9. Paired with a positive case under /ords that does qualify and correctly yields 24.1.5.

server.ListenAndServe() is called directly with no signal handling or graceful shutdown. 31/35 other testdata mock servers implement signal.Notify + srv.Shutdown(ctx) (like testdata/zyxel/server.go).
Recommend adding the standard signal-handling pattern before ListenAndServe.
There was a problem hiding this comment.
Done in 41ac886 — your 31/35 count is exact, I checked before changing anything. Adopted the testdata/zyxel/server.go pattern verbatim: signal.Notify on SIGINT/SIGTERM, ListenAndServe in a goroutine tolerating http.ErrServerClosed, then Shutdown with a 5s context.
Before and after, same SIGTERM:
old: exit 143 (128+15, killed outright, no shutdown line)
new: exit 0 "Received signal terminated, shutting down..."
It matters more here than in most testdata mocks because the compose file runs four services off this image, so docker compose down sends SIGTERM to all of them before its kill timer.
One deliberate deviation from zyxel: I kept the startup line as fmt.Printf rather than zyxel's log.Printf. Using log.Printf there regressed gosec from 0 to 1 —
[server.go:140] G706 (CWE-117): Log injection via taint analysis
log.Printf("ORDS mock (mode=%s) listening on %s", mode, addr)
— because mode and addr are os.Getenv-derived and gosec taints them into log.*. It's pre-existing across the convention (zyxel itself reports 4 G706, adminpath 5), so gosec clearly isn't gating testdata today, but this file was at 0 and gosec is a required check on this PR, so I didn't want to hand it a new finding. The shutdown block's own log.Fatalf/log.Printf calls take an error and an os.Signal, so they don't trip it. gosec ./testdata/oracleords/... reports 0 issues.
Happy to switch it to log.Printf for exact consistency if you'd rather the convention win over the gosec count — say the word.

@anushkavirgaonkar three small comments and then I think this is good to go
Three findings from human review on #422, all valid. 1. The "?v=" capture had no trailing boundary, so a malformed "?v=24.1.5abc" silently captured "24.1.5" and reported a version the response never stated. RE2 has no lookahead, so the fix is an explicit terminator alternation, "(?:[\"'\\s>&<)]|$)", after the capture. The other two patterns already self-terminate on "/". Verified that every legitimate form still matches: quote-terminated, end of body, CSS url(), and "&"-separated. 2. evaluateORDS extracted the version whenever ev.hasAPEXHeader was true, without checking apexBody -- the variable that actually carries the bodyHasAPEXProduct guarantee. That contradicted this file's own documented invariant ("the version is read from that same qualifying body"), and let a genuine APEX response carrying an unrelated "/i/9.9.9/themes/..." asset stamp a wrong version onto the CPE. An X-APEX-* header proves the SERVICE is APEX; it says nothing about the body it arrived with. Gated on apexBody. 3. testdata/oracleords/server.go called ListenAndServe directly with no signal handling, where 31 of the 35 other testdata mocks use signal.Notify + srv.Shutdown(ctx). Adopted that pattern from testdata/zyxel/server.go; the MODE stays visible on startup because the compose file runs four of them. The reviewer's scenario from (2) is now a test case that fails without the gate. 75 subtests green; all four testdata modes re-validated end to end.

Problem
The ORDS/APEX fingerprinter reads the version from a
Server: Oracle-REST-Data-Services/<ver>header. Modern ORDS emits noServer,X-ORDS-*,X-APEX-*orX-Powered-Byheader at all, so on current deployments the plugin detects ORDS but reportsversion: *, which defeats CVE/KEV matching.Investigation
Validated against a live ORDS 26.2.3 standalone instance built from Oracle's published
ords-latest.zip, plus static analysis of the shippedords.war.What is served anonymously, and what it contains:
/ords/,/ords/_/landing,/Serverheader/ords/_/landing/css/style.css,/ords/_/lib/*,/ords/_/jet/*/ords/sign-in/,/ords/oauth/config.jsoauth/config.jsreports its ownproductVersion: '1.0.0')/ords/nonexistentapplication/problem+json, no version/ords/_/instance-api/*,/ords/_/db-api/*,/ords/_/sqlWhat does work:
/ords/_sdw/js/config.js— the Database Actions / SQL Developer Web client config — carries"productName":"SQL Developer","productVersion":"26.2.0". It is plain static content fromords-sdw-client-26.2.3.237.1104.jar, and the ORDS privilege definition that guards SDW (oracle.dbtools.sdw.userinMETA-INF/privileges/sdw_privilege.json) covers only/_sdw/_services/*— the/_sdw/js/*static tree is unprotected, so it reads anonymously wherever a database pool is configured.What was rejected, with evidence: ORDS returns a build-wide ETag on every
/ords/_/static resource (one value per build and locale, identical across files, stable across restarts and fresh configs) — it would identify a build exactly. But Oracle publishes onlyords-latest.zip; prior releases 404 at the public download path and need an account. An ETag-to-version table could neither be built nor kept current, so this is deliberately not attempted. That conclusion is documented in the plugin.Changes
/ords/_sdw/js/config.js, guarded on the body identifying itself as the SQL Developer client. Only<major>.<minor>is reported — SQL Developer Web pins the patch component at zero for the whole train (ORDS 26.2.3 ships"26.2.0"), and asserting an unobserved patch level would produce false CVE matches. The probe is gated on ORDS already being detected and no Server-header version, so non-ORDS hosts never see the extra request.?v=<ver>on an/i/asset, a versioned/i/<ver>/images directory, orstatic.oracle.com/cdn/apex/<ver>/. It now populates theapplication_expressCPE, which previously always used the wildcard, and is exposed asapex_versionon the payload. Only read from bodies that already qualified as APEX evidence.evaluateORDS/detectORDSreturn anordsResultstruct instead of four positional values, since the evaluation grew two more outputs.Validation
