An attacker exploiting the vulnerability in WIBU CodeMeter Runtime in server mode could gain full access to the affected server via network access without any user interaction. This could lead to remote code execution and escalation of privileges giving full admin access on the host system for an already authenticated user (logged in locally to the PC).",
