Descriptions

A vulnerability has been identified in Opcenter Execution Discrete (All versions < V3.2), Opcenter Execution Foundation (All versions < V3.2), Opcenter Execution Process (All versions < V3.2), Opcenter Intelligence (All versions < V3.3), Opcenter Quality (All versions < V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (All versions < V2.6), SIMATIC IT Production Suite (All versions < V8.0), SIMATIC Notifier Server for Windows (All versions), SIMATIC PCS neo (All versions < V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (All versions < V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 2), SIMOCODE ES V15.1 (All versions < V15.1 Update 4), SIMOCODE ES V16 (All versions < V16 Update 1), Soft Starter ES V15.1 (All versions < V15.1 Update 3), Soft Starter ES V16 (All versions < V16 Update 1). Sending multiple specially crafted packets to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself. On some cases the vulnerability could leak random information from the remote service.

Se ha identificado una vulnerabilidad en Opcenter Execution Discrete (Todas las versiones anteriores a V3.2), Opcenter Execution Foundation (Todas las versiones anteriores a V3.2), Opcenter Execution Process (Todas las versiones anteriores a V3.2), Opcenter Intelligence (Todas las versiones anteriores a V3.3), Opcenter Quality (Todas las versiones anteriores a V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (Todas las versiones anteriores a V2.6), SIMATIC IT Production Suite (Todas las versiones anteriores a V8. 0), SIMATIC Notifier Server for Windows (Todas las versiones), SIMATIC PCS neo (Todas las versiones anteriores a V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (Todas las versiones anteriores a V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (Todas las versiones anteriores a V16 Update 2), SIMOCODE ES V15. 1 (Todas las versiones anteriores a V15.1 Update 4), SIMOCODE ES V16 (Todas las versiones anteriores a V16 Update 1), Soft Starter ES V15.1 (Todas las versiones anteriores a V15.1 Update 3), Soft Starter ES V16 (Todas las versiones anteriores a V16 Update 1). El envío de múltiples paquetes especialmente diseñados al servicio afectado podría causar una denegación de servicio remota parcial, que haría que el servicio se reiniciara. En algunos casos la vulnerabilidad podría filtrar información aleatoria del servicio remoto
