Siemens SIMATIC S7-1500 CPU devices before 1.8.3 allow remote attackers to cause a denial of service (STOP mode transition) via crafted packets on TCP port 102. Dispositivos Siemens SIMATIC S7-1500 CPU en versiones anteriores a 1.8.3 permiten a atacantes remotos causar una denegación de servicio (transición al modo STOP) a través de paquetes manipulados sobre el puerto 102 TCP. • http://www.securityfocus.com/bid/83106 http://www.securitytracker.com/id/1034954 http://www.siemens.com/cert/pool/cert/siemens_security_advisory_ssa-253230.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-253230.pdf https://ics-cert.us-cert.gov/advisories/ICSA-16-040-02 • CWE-20: Improper Input Validation •
