Remote web-service operation execution in Apache CXF

CVE-2012-3451GHSA-55j7-f5wf-43m4

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.apache.cxf:cxf 2.6.2, 2.5.5, 2.4.9), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Apache CXF before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 allows remote attackers to execute unintended web-service operations by sending a header with a SOAP Action String that is inconsistent with the message body.

# Patch Next advisory brief: CVE-2012-3451

Advisory: Remote web-service operation execution in Apache CXF
IDs: CVE-2012-3451, GHSA-55j7-f5wf-43m4
Record: https://patchnext.com/advisories/cve-2012-3451 (revision 1, source checked 26 Oct 2026, 16:21 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Unrated
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.cxf:cxf 2.6.2, 2.5.5, 2.4.9. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.cxf:cxf: affected < 2.4.9; >= 2.5.0, < 2.5.5; >= 2.6.0, < 2.6.2; fixed in 2.5.5, 2.4.9, 2.6.2

## Suggested inspection (read-only)
- Maven org.apache.cxf:cxf: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.cxf:cxf.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-55j7-f5wf-43m4 (GitHub-reviewed advisory GHSA-55j7-f5wf-43m4 lists affected ranges: Maven org.apache.cxf:cxf >=0 =2.5.0 =2.6.0 <2.6.2)

Commands are suggestions: review each one before running it.
