Mitigation candidate

A defect of the type ARMR addresses, with a fix path to work from and a working exploit already published. This is a claim on attention, not a scheduling commitment: no rule exists and none is scheduled.

Protection none
Action unverified patch rule
Review automated inferred
Record active

Decided by patch-hint : A reference pointing at the upstream fix: a commit, a PR, a Red Hat bug

Finding A reference points at an upstream fix (redhat-cve tier): https://access.redhat.com/security/cve/CVE-2012-1723. That makes this CVE a candidate for an ARMR patch rule — it is the kind of defect ARMR can address, and there is a fix to work from. No rule exists and none is scheduled: writing one means reading the linked change and finding a hook point ARMR can express it at, which may turn out not to exist.

Candidate fix https://access.redhat.com/security/cve/CVE-2012-1723 : a Red Hat CVE page: the weakest tier, pinning no commit, but its existence means Red Hat triaged and shipped the CVE

# Rule Outcome Status Detail

identity: Does this identifier describe a vulnerability at all? first match wins

1 rejected no-match CVE Program withdrawal of this identifier

scope: Is the vulnerability ARMR's to address? first match wins

2 armr-patch-file no-match An ARMR patch file on disk for this CVE

3 armr-secure-rule-file no-match An ARMR security-rule template on disk for this CVE

4 manual-classification no-match A researcher's recorded decision for this specific CVE

5 manual classification no-match Manual classification of this CVE in the legacy dataset

6 non-java-upstream no-match A root cause in non-Java code: an OS kernel, a C library, or a bundled runtime

7 oracle-component no-match The defect being in a component of a tracked product the agent does not reach: JavaFX, the Java SE installer, the native WebLogic proxy plug-in. Oracle gives these no CPE of their own and names them only in the description.

8 osv-maven no-match An OSV.dev record of this CVE affecting a package published to Maven Central

9 cna-maven-package no-match An affected Maven artifact named by the CNA itself

10 known-cpe-product matched Queued for review Matches known products: oracle/jdk, oracle/jre

11 cna-cpe-product not-reached A CPE the CNA published naming a tracked product. Oracle publishes these on advisory day, months before NVD.

12 oracle-advisory-family not-reached A tracked product family named in Oracle's own risk matrix. CPE cannot carry a suite name, only a module.

13 non-deployable-product not-reached The only affected product being a sealed appliance image, where Java runs but no -javaagent can be attached

14 unmatched-product not-reached No tracked product matched above, and none present at all

disposition: What do we do about one that is? cumulative: every rule gets a turn

15 patch-hint decided it matched Mitigation candidate References include candidate fix URL (redhat-cve tier): https://access.redhat.com/security/cve/CVE-2012-1723 (from RHSA-2012:0729)

16 open-source-maven skipped The affected package being open source on Maven, so the fix can be read

17 poc-derivable skipped An indexed exploit to reverse-engineer, where there is no source to read

18 no-exploit skipped With no fix path, a public exploit, or a CISA record of one

19 secure-rule-match no-match A vulnerability class already blocked by an ARMR security rule

20 below-action-threshold no-match Severity is CRITICAL — only MEDIUM/LOW are deprioritized

21 no-exploit-published no-match A KEV listing, a CISA verdict of active exploitation, or a reviewed exploit catalogue carries this CVE — somebody has published a working exploit, so it stays a candidate
