CVE-2022-34820: Command Injection
First published: Tue Jul 12 2022(Updated: )
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.
