path admin.php↗

• → Monitor HTTP requests to admin.php with the query parameters page=history and filter_user_id for SQL injection payloads (e.g., UNION SELECT, quotes, comment sequences) indicating exploitation of CVE-2023-26876. ↗
• → The Metasploit auxiliary module targets authenticated sessions to extract usernames and encrypted passwords via SQL injection in the filter_user_id parameter; look for authenticated admin sessions making unusual or repeated requests to the history page with anomalous filter_user_id values. ↗

• · Exploitation requires an authenticated session; unauthenticated attackers cannot directly exploit this endpoint. Detection should account for the attacker already possessing valid Piwigo credentials. ↗
• · Affected versions are Piwigo v13.5.0 and earlier; detections and mitigations should be scoped to these versions. ↗
