VAR-202505-1698

Vulnerability from variot - Updated: 2025-08-26 21:48

A vulnerability has been identified in SIMATIC PCS neo V4.1 (All versions < V4.1 Update 3), SIMATIC PCS neo V5.0 (All versions < V5.0 Update 1). Affected products do not correctly invalidate user sessions upon user logout. This could allow a remote unauthenticated attacker, who has obtained the session token by other means, to re-use a legitimate user's session even after logout. Siemens' SIMATIC PCS neo contains a session expiration vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state
