TITLE

Siemens SIMATIC S7-1500 CPU PLC Service disruption in device firmware (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2014-001712

DESCRIPTION

Siemens SIMATIC S7-1500 CPU PLC devices with firmware before 1.5.0 allow remote attackers to cause a denial of service (defect-mode transition) via crafted HTTP packets. Supplementary information : CWE Vulnerability type by CWE-404: Improper Resource Shutdown or Release ( Improper shutdown and release of resources ) Has been identified. Siemens SIMATIC is an automation software in a single engineering environment. Siemens SIMATIC S7-1500 failed to properly handle specially crafted messages sent to the 80/tcp (HTTP) port, allowing remote attackers to exploit the vulnerability to send specially crafted requests to put the device into defect mode, requiring a restart to resume normal functionality. Siemens SIMATIC S7-1500 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 S7-1500 1.5.0 are vulnerable
