An Improper Input Validation issue was discovered in Siemens SIMATIC PCS 7 V8.1 prior to V8.1 SP1 with WinCC V7.3 Upd 13, and V8.2 all versions. The improper input validation vulnerability has been identified, which may allow an authenticated remote attacker who is a member of the administrators group to crash services by sending specially crafted messages to the DCOM interface. SIMATIC PCS 7 is a set of distributed process control systems using WinCC from Siemens AG, Germany. Siemens SIMATIC PCS 7 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
