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 does not correctly escape some user provided fields during the authentication process. This could allow an attacker to inject custom commands and execute arbitrary code with elevated privileges.

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 no escapa correctamente de algunos campos proporcionados por el usuario durante el proceso de autenticación. Esto podría permitir a un atacante inyectar comandos personalizados y ejecutar código arbitrario con privilegios elevados
