						Description
						
							
							
								
							
								
A vulnerability has been identified in SIMATIC Drive Controller family (All versions < V3.0.1), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl. SIPLUS variants) (All versions), SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions < V4.6.0), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V3.0.1), SIMATIC S7-1500 Software Controller (All versions), SIMATIC S7-PLCSIM Advanced (All versions < V5.0), SIPLUS TIM 1531 IRC (All versions), TIM 1531 IRC (All versions). Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial-of-service in the device.
