CVE-2023-34865Network attack vector

Arbitrary file relocation via rename path traversal

Published Jun 14, 2023 · Updated Jan 3, 2025

Path traversal in the rename feature of ujcms 6.0.2 allows remote attackers to move files outside the managed directory. The feature accepts a crafted destination pathname containing traversal elements and applies it to the filesystem move operation without confining the resolved path. No authentication or user interaction is required; successful requests can relocate files accessible to the server process, affecting their integrity and availability.
