Description

A relative path traversal vulnerability in a FileUtil class used by the PEAR management component of Apache UIMA allows an attacker to create files outside the designated target directory using carefully crafted ZIP entry names. This issue affects Apache UIMA Apache UIMA version 3.3.0 and prior versions. Note that PEAR files should never be installed into an UIMA installation from untrusted sources because PEAR archives are executable plugins that will be able to perform any actions with the same privileges as the host Java Virtual Machine.

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.uima:uimaj-core, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.uima:uimaj-core to 3.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-32287 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
