VAR-202011-1492
Vulnerability from variot - Updated: 2023-12-18 13:23A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions), SIMATIC TDC CPU555 (All versions), SINUMERIK 840D sl (All versions). Sending multiple specially crafted packets to the affected devices could cause a Denial-of-Service on port 102. A cold restart is required to recover the service. Several Siemens products contain resource exhaustion vulnerabilities.Denial of service (DoS) It may be put into a state. Siemens SIMATIC S7-300 CPUs are a CPU (Central Processing Unit) module of Siemens (Siemens), Germany. Siemens SINUMERIK 840D sl is a set of advanced machine tool CNC system from Siemens (Siemens) in Germany.
Siemens SIMATIC S7-300 CPUs and SINUMERIK Controller have a denial of service vulnerability
