Arbitrary file deletion via path traversal
Published Apr 26, 2024 · Updated Aug 2, 2024
Path traversal in lib/admin/image.admin.php in CmsEasy 7.7.7.9 allows remote attackers to delete arbitrary files via a crafted GET request. The image administration endpoint uses attacker-controlled path input to select a deletion target without rejecting traversal segments that escape the intended directory. No authentication or user interaction is required; successful requests can remove files writable by the PHP process, with no reported data disclosure or code execution.
