Vulnerability from variot
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 ISO-TSAP packets. Supplementary information : CWE Vulnerability types 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. The Siemens SIMATIC S7-1500 fails to properly handle specially crafted messages sent to the 102/TCP (ISO-TSAP) port, allowing remote attackers to exploit the vulnerability to send specially crafted requests to put the device into defect mode and to restart the normal function. 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
