Vulnerability from variot
A vulnerability has been identified in SIMATIC CP 1626 (All versions), SIMATIC ET 200SP Open Controller CPU 1515SP PC (incl. SIPLUS variants) (All versions), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl. SIPLUS variants) (All versions < V20.8), SIMATIC HMI Panel (incl. SIPLUS variants) (All versions), SIMATIC NET PC Software V14 (All versions < V14 SP1 Update 14), SIMATIC NET PC Software V15 (All versions), SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions < V4.4.0), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V2.8.1), SIMATIC S7-1500 Software Controller (All versions < V20.8), SIMATIC S7-PLCSIM Advanced (All versions < V3.0), SIMATIC STEP 7 (TIA Portal) (All versions < V16), SIMATIC WinCC (TIA Portal) (All versions < V16), SIMATIC WinCC OA (All versions < V3.16 P013), SIMATIC WinCC Runtime Advanced (All versions < V16), SIMATIC WinCC Runtime Professional (All versions < V16), TIM 1531 IRC (incl. SIPLUS NET variants) (All versions < V2.1). Affected devices contain a message protection bypass vulnerability due to certain properties in the calculation used for integrity protection. This could allow an attacker in a Man-in-the-Middle position to modify network traffic sent on port 102/tcp to the affected devices. plural SIMATIC The product contains an access control vulnerability.Information may be tampered with. The Simatic S7-1200 CPU and Simatic S7-1500 CPU series are discrete and continuous control in industrial environments such as manufacturing, food and beverage, and chemical industries. A man-in-the-middle attack vulnerability exists in the SIMATICS7-1200 and SIMATICS7-1500CPU families. The vulnerability could impact the integrity of the communication. No public exploitation of the vulnerability was known at the time of advisory publication. Both Siemens SIMATIC S7-1500 CPU and Siemens SIMATIC S7-1200 are products of Siemens, Germany. SIMATIC S7-1500 CPU is a CPU (central processing unit) module. Siemens SIMATIC S7-1200 is a S7-1200 series PLC (programmable logic controller). This vulnerability stems from network systems or products not properly restricting access to resources from unauthorized roles

SIPLUS NET variants) (All versions \u003c V2.1). Affected devices contain a message protection bypass vulnerability due to certain properties in the calculation used for integrity protection. This could allow an attacker in a Man-in-the-Middle position to modify network traffic sent on port 102/tcp to the affected devices. plural SIMATIC The product contains an access control vulnerability.Information may be tampered with. The Simatic S7-1200 CPU and Simatic S7-1500 CPU series are discrete and continuous control in industrial environments such as manufacturing, food and beverage, and chemical industries. A man-in-the-middle attack vulnerability exists in the SIMATICS7-1200 and SIMATICS7-1500CPU families. The vulnerability could impact the integrity of the communication. No public exploitation of the vulnerability was known at the time of advisory publication. Both Siemens SIMATIC S7-1500 CPU and Siemens SIMATIC S7-1200 are products of Siemens, Germany. SIMATIC S7-1500 CPU is a CPU (central processing unit) module. Siemens SIMATIC S7-1200 is a S7-1200 series PLC (programmable logic controller). This vulnerability stems from network systems or products not properly restricting access to resources from unauthorized roles",
