SIPLUS variants) (All versions < V8.1), SIMATIC WinAC RTX 2010 (All versions < V2010 SP3), SIMATIC WinAC RTX F 2010 (All versions < V2010 SP3), SINUMERIK 828D (All versions < V4.7 SP6 HF1), SIPLUS ET 200S IM151-8 PN/DP CPU (All versions < V3.2.16), SIPLUS ET 200S IM151-8F PN/DP CPU (All versions < V3.2.16), SIPLUS NET CP 443-1 (All versions < V3.3), SIPLUS NET CP 443-1 Advanced (All versions < V3.3), SIPLUS S7-300 CPU 314C-2 PN/DP (All versions < V3.3.16), SIPLUS S7-300 CPU 315-2 PN/DP (All versions < V3.2.16), SIPLUS S7-300 CPU 315F-2 PN/DP (All versions < V3.2.16), SIPLUS S7-300 CPU 317-2 PN/DP (All versions < V3.2.16), SIPLUS S7-300 CPU 317F-2 PN/DP (All versions < V3.2.16), SIPLUS S7-400 CPU 414-3 PN/DP V7 (All versions < V7.0.3), SIPLUS S7-400 CPU 416-3 PN/DP V7 (All versions < V7.0.3), Softnet PROFINET IO for PC-based Windows systems (All versions). Responding to a PROFINET DCP request with a specially crafted PROFINET DCP packet could cause a denial of service condition of the requesting system.
The security vulnerability could be exploited by an attacker located on the same Ethernet segment (OSI Layer 2) as the targeted device. A manual restart is required to recover the system.

CPUs ET200 relacionadas y variantes SIPLUS) (Todas las versiones anteriores a V1.7.0), Software Controller SIMATIC S7-1500 (incl. F) (Todas las versiones anteriores a V1.7.0), familia de CPUs SIMATIC S7-300 (incl. CPUs ET200 relacionadas y variantes SIPLUS) (Todas las versiones anteriores a V3.X.16 ), familia de CPU SIMATIC S7-400 H V6 (incl. variantes SIPLUS) (Todas las versiones anteriores a V6.0.9), familia de CPU SIMATIC S7-400 PN/DP V6 (incl. variantes SIPLUS) (Todas las versiones anteriores a V6.0.7), familia de CPU SIMATIC S7-400 PN/DP V7 (incl. variantes SIPLUS) (Todas las versiones), familia de CPU SIMATIC S7-410 (incl. variantes SIPLUS) (Todas las versiones). SIPLUS) (Todas las versiones anteriores a V8.1), SIMATIC WinAC RTX (F) 2010 (Todas las versiones anteriores a SIMATIC WinAC RTX 2010 SP3), SINUMERIK 828D (Todas las versiones anteriores a V4.7 SP6 HF1), Softnet PROFINET IO para sistemas Windows basados en PC (Todas las versiones). La respuesta a una solicitud PROFINET DCP con un paquete PROFINET DCP especialmente diseñado podría causar una condición de denegación de servicio del sistema solicitante. La vulnerabilidad de seguridad podría ser explotada por un atacante situado en el mismo segmento Ethernet (capa 2 de OSI) que el dispositivo objetivo. El éxito de la explotación no requiere ninguna interacción del usuario o privilegios y afecta a la disponibilidad de la funcionalidad principal del dispositivo afectado. Se requiere un reinicio manual para recuperar el sistema. En el momento de la publicación del aviso no se conoce ninguna explotación pública de esta vulnerabilidad de seguridad. Siemens proporciona mitigaciones para resolver el problema de seguridad. Las interfaces PROFIBUS no están afectadas.
