Description

A vulnerability has been identified in SIMATIC NET CP 342-5 (incl. SIPLUS variants) (All versions), SIMATIC NET CP 343-1 Advanced (incl. SIPLUS variants) (All versions < V3.0.44), SIMATIC NET CP 343-1 Lean (incl. SIPLUS variants) (All versions < V3.1.1), SIMATIC NET CP 343-1 Standard (incl. SIPLUS variants) (All versions < V3.1.1), SIMATIC NET CP 443-1 Advanced (incl. SIPLUS variants) (All versions < V3.2.9), SIMATIC NET CP 443-1 Standard (incl. SIPLUS variants) (All versions < V3.2.9), SIMATIC NET CP 443-5 Basic (incl. SIPLUS variants) (All versions), SIMATIC NET CP 443-5 Extended (All versions), TIM 3V-IE / TIM 3V-IE Advanced (incl. SIPLUS NET variants) (All versions < V2.6.0), TIM 3V-IE DNP3 (incl. SIPLUS NET variants) (All versions < V3.1.0), TIM 4R-IE (incl. SIPLUS NET variants) (All versions < V2.6.0), TIM 4R-IE DNP3 (incl. SIPLUS NET variants) (All versions < V3.1.0). The implemented access protection level enforcement of the affected communication processors (CP) could possibly allow unauthenticated users to perform administrative operations on the CPs if network access (port 102/TCP) is available and the CPs' configuration was stored on their corresponding CPUs.
