Descriptions
A vulnerability has been identified in SIMATIC S7-400 CPU 412-1 DP V7 (All versions), SIMATIC S7-400 CPU 412-2 DP V7 (All versions), SIMATIC S7-400 CPU 414-2 DP V7 (All versions), SIMATIC S7-400 CPU 414-3 DP V7 (All versions), SIMATIC S7-400 CPU 414-3 PN/DP V7 (All versions < V7.0.3), SIMATIC S7-400 CPU 414F-3 PN/DP V7 (All versions < V7.0.3), SIMATIC S7-400 CPU 416-2 DP V7 (All versions), SIMATIC S7-400 CPU 416-3 DP V7 (All versions), SIMATIC S7-400 CPU 416-3 PN/DP V7 (All versions < V7.0.3), SIMATIC S7-400 CPU 416F-2 DP V7 (All versions), SIMATIC S7-400 CPU 416F-3 PN/DP V7 (All versions < V7.0.3), SIMATIC S7-400 CPU 417-4 DP V7 (All versions), SIMATIC S7-400 CPU 412-2 PN V7 (All versions < V7.0.3), SIMATIC S7-400 H V4.5 and below CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-400 H V6 CPU family (incl. SIPLUS variants) (All versions < V6.0.9), SIMATIC S7-400 PN/DP V6 and below CPU family (incl. SIPLUS variants) (All versions), SIMATIC S7-410 CPU family (incl. SIPLUS variants) (All versions < V8.2.1), 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), SIPLUS S7-400 CPU 416-3 V7 (All versions), SIPLUS S7-400 CPU 417-4 V7 (All versions). Sending of specially crafted packets to port 102/tcp via Ethernet interface
via PROFIBUS or Multi Point Interfaces (MPI) could cause a denial of service
condition on affected devices. Flashing with a firmware image may be required
to recover the CPU.
Successful exploitation requires an attacker to have network access to port
102/tcp via Ethernet interface or to be able to send messages via PROFIBUS or
Multi Point Interfaces (MPI) to the device. No user interaction is required.
If no access protection is configured, no privileges are required to exploit
the security vulnerability. The vulnerability could allow causing a
denial of service condition of the core functionality of the CPU,
compromising the availability of the system.
Se ha identificado una vulnerabilidad en la familia de CPUs SIMATIC S7-400 DP V7 (incl. variantes SIPLUS) (Todas las versiones), la familia de CPUs SIMATIC S7-400 H V4.5 e inferiores (incl. variantes SIPLUS) (Todas las versiones), la familia de CPUs SIMATIC S7-400 H V6 (incl. variantes SIPLUS) (Todas las versiones). SIPLUS) (Todas las versiones anteriores a V6.0.9), familia de CPU SIMATIC S7-400 PN/DP V6 e inferiores (incl. variantes SIPLUS) (Todas las versiones), familia de CPU SIMATIC S7-410 (incl. variantes SIPLUS) (Todas las versiones anteriores a V8.2.1). El envío de paquetes especialmente diseñados al puerto 102/tcp a través de la interfaz Ethernet mediante PROFIBUS o interfaces multipunto (MPI) podría provocar una condición de denegación de servicio en los dispositivos afectados. Puede ser necesario un flasheo con una imagen de firmware para recuperar la CPU. El éxito de la explotación requiere que un atacante tenga acceso a la red al puerto 102/tcp a través de la interfaz Ethernet o que pueda enviar mensajes a través de PROFIBUS o Multi Point Interfaces (MPI) al dispositivo. No se requiere ninguna interacción con el usuario. Si no se configura ninguna protección de acceso, no se requieren privilegios para explotar la vulnerabilidad de seguridad. La vulnerabilidad podría permitir causar una condición de denegación de servicio de la funcionalidad del núcleo de la CPU, comprometiendo la disponibilidad del sistema
