Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 25.1.102 and Application prior to version 25.1.1413 (Windows client deployments) contain a registry key that can be enabled by administrators, causing the client to skip SSL/TLS certificate validation. An attacker who can intercept HTTPS traffic can then inject malicious driver DLLs, resulting in remote code execution with SYSTEM privileges; a local attacker can achieve local privilege escalation via a junction‑point DLL injection. This vulnerability has been confirmed to be remediated, but it is unclear as to when the patch was introduced.
Weakness
The product does not validate, or incorrectly validates, a certificate.
