A vulnerability has been identified in SIPROTEC 5 relays with CPU variants CP050 (All versions < V8.80), SIPROTEC 5 relays with CPU variants CP100 (All versions < V8.80), SIPROTEC 5 relays with CPU variants CP300 (All versions < V8.80). Received webpackets are not properly processed. An unauthenticated remote attacker with access to any of the Ethernet interfaces could send specially crafted packets to force a restart of the target device. Se ha identificado una vulnerabilidad en los relés SIPROTEC 5 con variantes de CPUCP050 (Todas las versiones anteriores a V8.80), relés SIPROTEC 5 con variantes de CPUCP100 (Todas las versiones anteriores a V8.80), relés SIPROTEC 5 con variantes de CPUCP300 (Todas las versiones anteriores a V8.80).

A vulnerability has been identified in Firmware variant IEC 61850 for EN100 Ethernet module (All versions < V4.35), Firmware variant MODBUS TCP for EN100 Ethernet module (All versions), Firmware variant DNP3 TCP for EN100 Ethernet module (All versions), Firmware variant IEC104 for EN100 Ethernet module (All versions), Firmware variant Profinet IO for EN100 Ethernet module (All versions), SIPROTEC 5 relays with CPU variants CP300 and CP100 and the respective Ethernet communication modules (All versions < V7.82), SIPROTEC 5 relays with CPU variants CP200 and the respective Ethernet communication modules (All versions < V7.58). Specially crafted packets to port 102/tcp could cause a denial-of-service condition in the affected products. A manual restart is required to recover the EN100 module functionality of the affected devices. Successful exploitation requires an attacker with network access to send multiple packets to the affected products or modules. As a precondition the IEC 61850-MMS communication needs to be activated on the affected products or modules. • https://cert-portal.siemens.com/productcert/pdf/ssa-104088.pdf •
