CVE-2020-12832Known exploitationNetwork attack vector

Arbitrary file deletion via pathname traversal

Published May 13, 2020 · Updated Aug 4, 2024

Path traversal in Simple File List before 4.2.8 allows remote attackers to delete arbitrary files through front-side file management. The front-side deletion path accepts a user-controlled pathname containing .. and removes the resolved file without ensuring that it remains within the configured file-list directory. The affected path is reachable when front-side file management is enabled on a non-Linux host, and deletion is limited to files writable by the web-server process.
