Vulnerability from variot
A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions < V3.X.17), SIMATIC TDC CP51M1 (All versions < V1.1.8), SIMATIC TDC CPU555 (All versions < V1.1.1), SINUMERIK 840D sl (All versions < V4.8.6), SINUMERIK 840D sl (All versions < V4.94). Specially crafted packets sent to port 102/tcp (Profinet) could cause the affected device to go into defect mode. A restart is required in order to recover the system. Successful exploitation requires an attacker to have network access to port 102/tcp, with no authentication. No user interation is required. At the time of advisory publication no public exploitation of this security vulnerability was known. SIMATIC S7-300n and SINUMERIK 840D sl Exists in a resource exhaustion vulnerability.Service operation interruption (DoS) It may be put into a state. Siemens SIMATIC S7-300 CPU is a modular general-purpose controller for the manufacturing industry from Siemens.
Siemens SIMATIC S7-300 CPU and SINUMERIK Controller have a resource management error vulnerability, which can be exploited by an attacker to cause a denial of service

"data": "A vulnerability has been identified in SIMATIC S7-300 CPU family (incl. related ET200 CPUs and SIPLUS variants) (All versions \u003c V3.X.17), SIMATIC TDC CP51M1 (All versions \u003c V1.1.8), SIMATIC TDC CPU555 (All versions \u003c V1.1.1), SINUMERIK 840D sl (All versions \u003c V4.8.6), SINUMERIK 840D sl (All versions \u003c V4.94). Specially crafted packets sent to port 102/tcp (Profinet) could cause the affected device to go into defect mode. A restart is required in order to recover the system. Successful exploitation requires an attacker to have network access to port 102/tcp, with no authentication. No user interation is required. At the time of advisory publication no public exploitation of this security vulnerability was known. SIMATIC S7-300n and SINUMERIK 840D sl Exists in a resource exhaustion vulnerability.Service operation interruption (DoS) It may be put into a state. Siemens SIMATIC S7-300 CPU is a modular general-purpose controller for the manufacturing industry from Siemens. \n\r\n\r\nSiemens SIMATIC S7-300 CPU and SINUMERIK Controller have a resource management error vulnerability, which can be exploited by an attacker to cause a denial of service",
