Vulnerability from variot

A vulnerability has been identified in SIMATIC S7-200 SMART CPU family (All versions >= V2.2 < V2.5.1). Affected devices do not properly handle large numbers of new incomming connections and could crash under certain circumstances. An attacker may leverage this to cause a Denial-of-Service situation. SIMATIC S7-200 SMART CPU Is vulnerable to a resource exhaustion.Denial of service (DoS) It may be put in a state. Siemens SIMATIC S7-200 Smart is a programmable logic controller (PLC) of Germany's Siemens (Siemens) company used in small and medium-sized automation systems. Attackers can use vulnerabilities to cause denial of service
