CVE-2025-53120Public exploitNetwork attack vector

Unauthenticated code execution via traversal file overwrite

Published Aug 25, 2025 · Updated Aug 25, 2025

Path traversal in Securden Unified PAM 9.0.x through 11.3.1 allows remote attackers to overwrite server files through an upload request. The unauthenticated /accountapp/upload_web_recordings_from_api_server endpoint accepts traversal sequences in file_name and relative_path and writes uploaded content outside its recordings directory. Overwriting the default postgresBackup.bat with a script executes attacker-supplied commands when a database backup runs.
