VAR-202502-0219

Vulnerability from variot - Updated: 2025-07-13 23:33

A vulnerability has been identified in SIMATIC PCS neo V4.0 (All versions), SIMATIC PCS neo V4.1 (All versions < V4.1 Update 2), SIMATIC PCS neo V5.0 (All versions < V5.0 Update 1), SIMOCODE ES V19 (All versions < V19 Update 1), SIRIUS Safety ES V19 (TIA Portal) (All versions < V19 Update 1), SIRIUS Soft Starter ES V19 (TIA Portal) (All versions < V19 Update 1), TIA Administrator (All versions < V3.0.4). 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. SIMATIC PCS neo is a new generation of distributed control system (DCS) launched by Siemens. It is designed based on the Web platform and HTML5 technology, specially designed for process industry, and supports multi-user collaborative work and digital management. TIA Administrator is a management tool in Siemens Industrial Automation Software Suite, mainly used for centralized management and maintenance of TIA Portal projects. Totally Integrated Automation Portal (TIA Portal) is a fully integrated automation software platform launched by Siemens, which aims to simplify the automation project development process through a unified engineering environment.

Siemens SIMATIC PCS neo, TIA Administrator, and Totally Integrated Automation Portal have insufficient session expiration vulnerabilities
