Simatic Wincc V8 1
Monthly
Authenticated database users can escalate privileges and execute arbitrary operating-system commands on hosts running SIMATIC WinCC V7.5 (all versions), V8.0 before Update 11, and V8.1 before Update 7 because the application assigns excessive permissions to a database role (CWE-266). Exploitation requires a remote attacker to already hold valid database credentials and network reachability to the WinCC database service, but no user interaction is needed; no public exploit code has been identified at time of analysis. Siemens rates the issue 8.7, and while the impact is high, our independent assessment classifies it as a credible operational-technology priority rather than an emergency because the prerequisite of authenticated database access and network segmentation limits the realistic attack surface.
