Vulnerability from variot
A vulnerability has been identified in SIMATIC Drive Controller family (All versions >= V2.9.2 < V2.9.4), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl. SIPLUS variants) (All versions >= V21.9 < V21.9.4), SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (All versions >= V4.5.0 < V4.5.2), SIMATIC S7-1500 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions >= V2.9.2 < V2.9.4), SIMATIC S7-1500 Software Controller (All versions >= V21.9 < V21.9.4), SIMATIC S7-PLCSIM Advanced (All versions >= V4.0 < V4.0 SP1), SIPLUS TIM 1531 IRC (All versions < V2.3.6), TIM 1531 IRC (All versions < V2.3.6). An unauthenticated attacker could cause a denial-of-service condition in a PLC when sending specially prepared packets over port 102/tcp. A restart of the affected device is needed to restore normal operations. Multiple Siemens products are vulnerable to lack of freeing memory after expiration.Service operation interruption (DoS) It may be in a state. The SIMATIC S7-1200 CPU family products are designed for discrete and continuous control in industrial environments such as the global manufacturing, food and beverage, and chemical industries. The SIMATIC S7-1500 CPU family products are designed for discrete and continuous control in industrial environments such as the global manufacturing, food and beverage, and chemical industries. The SIMATIC S7-1500 Software Controller is the SIMATIC software controller for PC-based automation solutions. SIMATIC S7-PLCSIM Advanced simulates the S7-1200, S7-1500 and some other PLC derivatives. Includes full network access to simulated PLCs, even in virtualized environments. SIPLUS extreme products are designed for reliable operation under extreme conditions, based on SIMATIC, LOGO! , SITOP, SINAMICS, SIMOTION, SCALANCE or other devices. The TIM 1531 IRC is a communication module.
Several Siemens industrial products have denial-of-service vulnerabilities that attackers can exploit to create denial-of-service conditions in PLCs

"data": "A vulnerability has been identified in SIMATIC Drive Controller family (All versions \u003e= V2.9.2 \u003c V2.9.4), SIMATIC ET 200SP Open Controller CPU 1515SP PC2 (incl.

An unauthenticated attacker could cause a denial-of-service condition in a PLC when sending specially prepared packets over port 102/tcp. A restart of the affected device is needed to restore normal operations. Multiple Siemens products are vulnerable to lack of freeing memory after expiration.Service operation interruption (DoS) It may be in a state. The SIMATIC S7-1200 CPU family products are designed for discrete and continuous control in industrial environments such as the global manufacturing, food and beverage, and chemical industries. The SIMATIC S7-1500 CPU family products are designed for discrete and continuous control in industrial environments such as the global manufacturing, food and beverage, and chemical industries. The SIMATIC S7-1500 Software Controller is the SIMATIC software controller for PC-based automation solutions. SIMATIC S7-PLCSIM Advanced simulates the S7-1200, S7-1500 and some other PLC derivatives. Includes full network access to simulated PLCs, even in virtualized environments. SIPLUS extreme products are designed for reliable operation under extreme conditions, based on SIMATIC, LOGO! , SITOP, SINAMICS, SIMOTION, SCALANCE or other devices. The TIM 1531 IRC is a communication module. \n\r\n\r\nSeveral Siemens industrial products have denial-of-service vulnerabilities that attackers can exploit to create denial-of-service conditions in PLCs",
