Vulnerability from variot
Siemens SIMATIC S7-300 CPU devices allow remote attackers to cause a denial of service (defect-mode transition) via crafted packets on (1) TCP port 102 or (2) Profibus. Siemens SIMATIC is an automation software in a single engineering environment. The Siemens SIMATIC S7-300 fails to correctly handle the messages sent by the user via Proibus to Port 102/TCP (ISO-TSAP), allowing the attacker to exploit the vulnerability to crash the application. Siemens SIMATIC S7-300 is prone to a denial-of-service vulnerability. Remote attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users. Siemens SIMATIC S7-300 CPU is a modular general-purpose controller used in the manufacturing industry by Siemens of Germany. A security vulnerability exists in Siemens SIMATIC S7-300 CPU devices
