TITLE

Siemens SIMATIC S7-1200 CPU PLC Service disruption on devices (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2014-001770

DESCRIPTION

Siemens SIMATIC S7-1200 CPU PLC devices with firmware before 4.0 allow remote attackers to cause a denial of service (defect-mode transition) via crafted ISO-TSAP packets, a different vulnerability than CVE-2014-2257. The SIMATIC S7-1200 is a programmable controller for simple but highly precise automation tasks. Siemens SIMATIC S7-1200 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. Versions prior to SIMATIC S7-1200 4.0 are vulnerable. Siemens SIMATIC S7-1200 CPU PLC is a programmable logic controller (PLC) used in small and medium-sized automation systems developed by Siemens in Germany
