VLAI
Summary
A vulnerability has been identified in SIMATIC WinCC V7.5 (All versions), SIMATIC WinCC V8.0 (All versions < V8.0 Update 11), SIMATIC WinCC V8.1 (All versions < V8.1 Update 7). The affected application does not sufficiently restrict the permissions assigned to a database role. This could allow an authenticated remote attacker with database access to escalate privileges and execute arbitrary commands on the host system where SIMATIC WinCC is installed, potentially leading to a compromise of the system.
