Description

jcp/xml/dsig/internal/dom/DOMCanonicalizationMethod.java in Apache Santuario XML Security for Java 1.4.x before 1.4.8 and 1.5.x before 1.5.5 allows context-dependent attackers to spoof an XML Signature by using the CanonicalizationMethod parameter to specify an arbitrary weak "canonicalization algorithm to apply to the SignedInfo part of the Signature."

Detection & mitigation playbook

Open-source dependency
  1. Detect

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

  2. Fix

    Update org.apache.santuario:xmlsec to 1.4.8 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2013-2172 is resolved across your whole dependency graph.

  3. Workarounds

    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.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2013-2172 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2013-2172. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.

Fixing This On Your OS

If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
