Unauthenticated file deletion via unsanitized filename
Published Apr 1, 2024 · Updated Aug 27, 2024
Path traversal in NUUO NVRmini 2 3.0.8 and earlier allows remote attackers to delete files through the web interface. The deletefile.php endpoint passes the filename parameter directly to PHP's unlink function without sanitization, so absolute paths and traversal sequences select files accessible to the web server. No authentication or user interaction is required, and deletion is limited to files writable by the web-server process.
