CVE-2022-32287Network attack vector

Arbitrary file write via PEAR ZIP traversal

Published Nov 3, 2022 · Updated May 2, 2025

Path traversal in Apache UIMA 3.3.0 and earlier allows attackers to write files outside the PEAR target via crafted ZIP entries. The PEAR management component's FileUtil extraction logic fails to ensure that a normalized ZIP entry path remains beneath the designated target directory. Exploitation requires installation of an untrusted PEAR archive and writes with the privileges of the host Java Virtual Machine.
