Descriptions

A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V3.X.17), SIMATIC TDC CP51M1 (All versions < V1.1.8), SIMATIC TDC CPU555 (All versions < V1.1.1), SINUMERIK 840D sl (All versions < V4.8.6), SINUMERIK 840D sl (All versions < V4.94). Specially crafted packets sent to port 102/tcp (Profinet) could cause the affected device to go into defect mode. A restart is required in order to recover the system. Successful exploitation requires an attacker to have network access to port 102/tcp, with no authentication. No user interation is required. At the time of advisory publication no public exploitation of this security vulnerability was known.

Se ha identificado una vulnerabilidad en SIMATIC S7-300 CPU family (incluyendo las variantes relacionadas a ET200 CPUs y SIPLUS) (Todas las versiones anteriores a V3.X.17), SIMATIC TDC CP51M1 (Todas las versiones anteriores a V1.1.8), SIMATIC TDC CPU555 (Todas las versiones anteriores a V1.1.1), SINUMERIK 840D sl (Todas las versiones anteriores a V4.8.6), SINUMERIK 840D sl (Todas las versiones anteriores a V4.94). Los paquetes especialmente diseñados enviados hacia el puerto 102/tcp (Profinet) pueden hacer que el dispositivo afectado entre en modo de defecto. Es requerido un reinicio para recuperar el sistema. Una explotación con éxito requiere que un atacante tenga acceso de red al puerto 102/tcp, sin autenticación. No es requerida una interacción del usuario. Al momento de la publicación del aviso no se conocía una explotación pública de esta vulnerabilidad de seguridad
