Summary

A vulnerability in SIMATIC WinCC V7.5, V8.0, and V8.1 is due to insufficient restriction of permissions assigned to a database role. An authenticated remote attacker with database access can escalate privileges and execute arbitrary commands on the host system where SIMATIC WinCC is installed, potentially leading to system compromise.

Risk Assessment

The risk includes the possibility of full compromise of the WinCC system, potentially leading to integrity and availability issues in industrial processes.

Recommendation

Update to the latest versions (V8.0 Update 11 or V8.1 Update 7) and restrict database role permissions.
