Descriptions

A vulnerability has been identified in SIMATIC CP 1242-7 V2 (All versions < V3.3.46), SIMATIC CP 1243-1 (All versions < V3.3.46), SIMATIC CP 1243-7 LTE EU (All versions < V3.3.46), SIMATIC CP 1243-7 LTE US (All versions < V3.3.46), SIMATIC CP 1243-8 IRC (All versions < V3.3.46), SIMATIC CP 1542SP-1 IRC (All versions >= V2.0 < V2.2.28), SIMATIC CP 1543-1 (All versions < V3.0.22), SIMATIC CP 1543SP-1 (All versions >= V2.0 < V2.2.28), SIPLUS ET 200SP CP 1542SP-1 IRC TX RAIL (All versions >= V2.0 < V2.2.28), SIPLUS ET 200SP CP 1543SP-1 ISEC (All versions >= V2.0 < V2.2.28), SIPLUS ET 200SP CP 1543SP-1 ISEC TX RAIL (All versions >= V2.0 < V2.2.28), SIPLUS NET CP 1242-7 V2 (All versions < V3.3.46), SIPLUS NET CP 1543-1 (All versions < V3.0.22), SIPLUS S7-1200 CP 1243-1 (All versions < V3.3.46), SIPLUS S7-1200 CP 1243-1 RAIL (All versions < V3.3.46). The application lacks proper validation of user-supplied data when parsing specific messages. This could result in a heap-based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of device.

Se ha identificado una vulnerabilidad en SIMATIC CP 1242-7 V2 (Todas las versiones anteriores a V3.3.46), SIMATIC CP 1243-1 (Todas las versiones anteriores a V3.3.46), SIMATIC CP 1243-7 LTE EU (Todas las versiones anteriores a V3.3.46), SIMATIC CP 1243-7 LTE US (Todas las versiones anteriores a V3. 3.46), SIMATIC CP 1243-8 IRC (Todas las versiones anteriores a V3.3.46), SIMATIC CP 1542SP-1 IRC (Todas las versiones posteriores o iguales a V2.0), SIMATIC CP 1543-1 (Todas las versiones anteriores a V3.0.22), SIMATIC CP 1543SP-1 (Todas las versiones posteriores o iguales a V2. 0), SIPLUS ET 200SP CP 1542SP-1 IRC TX RAIL (Todas las versiones posteriores o iguales a V2.0), SIPLUS ET 200SP CP 1543SP-1 ISEC (Todas las versiones posteriores o iguales a V2.0), SIPLUS ET 200SP CP 1543SP-1 ISEC TX RAIL (Todas las versiones posteriores o iguales a V2. 0), SIPLUS NET CP 1242-7 V2 (Todas las versiones anteriores a V3.3.46), SIPLUS NET CP 1543-1 (Todas las versiones anteriores a V3.0.22), SIPLUS S7-1200 CP 1243-1 (Todas las versiones anteriores a V3.3.46), SIPLUS S7-1200 CP 1243-1 RAIL (Todas las versiones anteriores a V3.3.46). La aplicación carece de una validación adecuada de los datos suministrados por el usuario al analizar mensajes específicos. Esto podría dar lugar a un desbordamiento del búfer basado en la pila. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del dispositivo
