The HMI web server in Siemens WinCC flexible 2004, 2005, 2007, and 2008 before SP3; WinCC V11 (aka TIA portal) before SP2 Update 1; the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime generates predictable authentication tokens for cookies, which makes it easier for remote attackers to bypass authentication via a crafted cookie.

Security readout for executives and security teams

Siemens HMI web server components generated predictable cookie authentication tokens. A remote attacker who can reach the affected web server could craft a cookie to bypass login. For executives, the main business risk is unauthorized access to industrial HMI interfaces if these systems are exposed beyond trusted OT networks. Exposure is most likely where affected Siemens HMI web server functions or runtimes are enabled and reachable by users or networks that should not have HMI access. Treat this as a high-priority OT exposure review, especially for sites with remotely reachable HMI web interfaces. The available evidence supports authentication bypass risk, but not confirmed active exploitation. Mitigation focus: Identify affected Siemens WinCC and SIMATIC HMI assets in OT inventories.; Review Siemens advisory SSA-345442 for exact fixed versions and upgrade guidance.; Prioritize WinCC flexible versions before 2008 SP3 and WinCC V11 before SP2 Update 1..
