CVE-2024-33350Public exploitNetwork attack vector

Arbitrary file overwrite via unfiltered path parameter

Published Apr 29, 2024 · Updated Aug 2, 2024

Path traversal in TaoCMS 3.0.2 allows remote authenticated users to overwrite files outside the CMS directory through its web interface. The File model copies the request's path parameter into SYS_ROOT without validation, then save() passes that path and attacker-controlled filedata to file_put_contents(). The published request targets the administrator endpoint with a PHP session cookie; code execution requires a writable executable PHP path, while other writable paths permit data modification.
