How do I fix CVE-2012-2378?

Update org.apache.cxf:cxf to 2.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2012-2378 is resolved across your whole dependency graph.

How do I detect CVE-2012-2378 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cxf:cxf, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2012-2378 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

Is CVE-2012-2378 actively exploited in the wild?

No public exploit code has been indexed for CVE-2012-2378 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2012-2378?

CVE-2012-2378 has an EPSS (Exploit Prediction Scoring System) score of 3.9%, placing it in the 90th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Description

Apache CXF 2.4.5 through 2.4.7, 2.5.1 through 2.5.3, and 2.6.x before 2.6.1, does not properly enforce child policies of a WS-SecurityPolicy 1.1 SupportingToken policy on the client side, which allows remote attackers to bypass the (1) AlgorithmSuite, (2) SignedParts, (3) SignedElements, (4) EncryptedParts, and (5) EncryptedElements policies.
