Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.843 and Application prior to 20.0.1923 (VA and SaaS deployments) contains dangerous PHP dead code present in multiple Docker-hosted PHP instances. A script named /var/www/app/resetroot.php (found in several containers) lacks authentication checks and, when executed, performs a SQL update that sets the database administrator username to root and its password hash to the SHA-512 hash of the string password. Separately, commented-out code in /var/www/app/lib/common/oses.php would unserialize session data (unserialize($_SESSION[osdata]))—a pattern that can enable remote code execution if re-enabled or reached with attacker-controlled serialized data. An attacker able to reach the resetroot.php endpoint can trivially reset the MySQL root password and obtain full database control; combined with deserialization issues this can lead to full remote code execution and system compromise. This vulnerability has been identified by the vendor as: V-2023-003 — Dead / Insecure PHP Code.
