A vulnerability has been identified in OpenPCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC BATCH V9.1 (All versions < V9.1 SP2 UC05), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC Route Control V9.1 (All versions < V9.1 SP2 UC05), SIMATIC WinCC Runtime Professional V18 (All versions < V18 Update 4), SIMATIC WinCC Runtime Professional V19 (All versions < V19 Update 2), SIMATIC WinCC V7.4 (All versions), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 15), SIMATIC WinCC V8.0 (All versions < V8.0 Update 4). The implementation of the RPC (Remote Procedure call) communication protocol in the affected products do not properly handle certain unorganized RPC messages. An attacker could use this vulnerability to cause a denial of service condition in the RPC server.

The implementation of the RPC (Remote Procedure call) communication protocol in the affected products do not properly handle certain malformed RPC messages. An attacker could use this vulnerability to cause a denial of service condition in the RPC server.

A vulnerability has been identified in OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions < V9.0 Upd4), OpenPCS 7 V9.1 (All versions), SIMATIC BATCH V8.2 (All versions), SIMATIC BATCH V9.0 (All versions), SIMATIC BATCH V9.1 (All versions), SIMATIC NET PC Software V14 (All versions), SIMATIC NET PC Software V15 (All versions), SIMATIC NET PC Software V16 (All versions < V16 Update 6), SIMATIC NET PC Software V17 (All versions < V17 SP1), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3 UC04), SIMATIC PCS 7 V9.1 (All versions < V9.1 SP1), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions), SIMATIC Route Control V9.1 (All versions), SIMATIC WinCC V15 and earlier (All versions < V15 SP1 Update 7), SIMATIC WinCC V16 (All versions < V16 Update 5), SIMATIC WinCC V17 (All versions < V17 Update 2), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 19), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 5). When downloading files, the affected systems do not properly neutralize special elements within the pathname. An attacker could then cause the pathname to resolve to a location outside of the restricted directory on the server and read unexpected critical files.
