TITLE

Siemens SIMATIC S7-300 CPU and SINUMERIK Controller Resource Management Error Vulnerability

Trust: 0.8

sources: IVD: 23361b8a-fcc5-462c-9762-a23bcf79ba39 // CNVD: CNVD-2020-19250

DESCRIPTION

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
