VAR-201805-1131

Vulnerability from variot - Updated: 2023-12-18 13:08

A vulnerability has been identified in SIMATIC S7-400 (incl. F) CPU hardware version 4.0 and below (All versions), SIMATIC S7-400 (incl. F) CPU hardware version 5.0 (All firmware versions < V5.2), SIMATIC S7-400H CPU hardware version 4.5 and below (All versions). The affected CPUs improperly validate S7 communication packets which could cause a Denial-of-Service condition of the CPU. The CPU will remain in DEFECT mode until manual restart. SIEMENS SIMATIC S7-400 CPU and SIMATIC S7-400H CPU Contains a data processing vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. The products in the Siemens SIMATIC S7-400 CPU family have been designed for process control in industrial environments. There is a denial of service vulnerability in the Siemens SIMATIC S7-400. Remote attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users. F) and SIMATIC S7-400H CPU. The vulnerability is caused by the fact that the program does not correctly verify the S7 communication data package. The following products and versions are affected: Siemens SIMATIC S7-400 4.0 and earlier, SIMATIC S7-400 (incl
