Authenticated file deletion via path traversal
Published Feb 1, 2022 · Updated Aug 3, 2024
Path traversal in eliteCMS 1.0 allows remote authenticated users to delete arbitrary server files through a crafted file parameter. The delete_image.php handler appends the unchecked file value to ../uploads/ and passes the resulting path to is_file and unlink without blocking parent-directory traversal. Access to the administrative endpoint requires a valid login, and deletion is limited to files accessible to the PHP process, potentially disrupting site operation or destroying application data.
