Published Apr 9, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Castle Rock SNMPc Online 12.10.10 before 2020-01-28 allows remote attackers to trigger administrative actions. The web application accepts state-changing GET requests, including CfgBackup.php4 backup-directory changes, without CSRF tokens or header-based origin checks. An authenticated operator must load attacker-controlled content; the forged request can alter the backup path and initiate a database backup.
