The WinCC server in Siemens SIMATIC WinCC 7.0 through SP3, 7.2 before Update 9, and 7.3 before Update 2; SIMATIC PCS 7 7.1 through SP4, 8.0 through SP2, and 8.1; and TIA Portal 13 before Update 6 allows remote attackers to execute arbitrary code via crafted packets.

A vulnerability has been identified in TIA Multiuser Server V14 (All versions), TIA Multiuser Server V15 (All versions < V15.1 Update 8), TIA Project-Server  (All versions < V1.1), TIA Project-Server V16 (All versions), TIA Project-Server V17 (All versions < V17 Update 6). Affected applications contain an untrusted search path vulnerability that could allow an attacker to escalate privileges, when tricking a legitimate user to start the service from an attacker controlled path.
