Summary

A vulnerability has been identified in Primary Setup Tool (PST) (All versions < V4.2 HF1), SIMATIC Automation Tool (All versions < V3.0), SIMATIC NET PC-Software (All versions < V14 SP1), SIMATIC PCS 7 V8.1 (All versions), SIMATIC PCS 7 V8.2 (All versions < V8.2 SP1), SIMATIC STEP 7 (TIA Portal) V13 (All versions < V13 SP2), SIMATIC STEP 7 (TIA Portal) V14 (All versions < V14 SP1), SIMATIC STEP 7 V5.X (All versions < V5.6), SIMATIC WinAC RTX 2010 SP2 (All versions), SIMATIC WinAC RTX F 2010 SP2 (All versions), SIMATIC WinCC (TIA Portal) V13 (All versions < V13 SP2), SIMATIC WinCC (TIA Portal) V14 (All versions < V14 SP1), SIMATIC WinCC V7.2 and prior (All versions), SIMATIC WinCC V7.3 (All versions < V7.3 Update 15), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Upd1), SIMATIC WinCC flexible 2008 (All versions < flexible 2008 SP5), SINAUT ST7CC (All versions installed in conjunction with SIMATIC WinCC < V7.3 Update 15), SINEMA Server (All versions < V14), SINUMERIK 808D Programming Tool (All versions < V4.7 SP4 HF2), SMART PC Access (All versions < V2.3), STEP 7 - Micro/WIN SMART (All versions < V2.3), Security Configuration Tool (SCT) (All versions < V5.0). Specially crafted PROFINET DCP broadcast packets sent to the affected products on a local Ethernet segment (Layer 2) could cause a Denial-of-Service condition of some services. The services require manual restart to recover.
