Siemens » Simatic Pcs7 : Security Vulnerabilities, CVEs, CVSS score >= 7

An XXE vulnerability has been identified in OPC Foundation UA .NET Sample Code before 2017-03-21 and Local Discovery Server (LDS) before 1.03.367. Among the affected products are Siemens SIMATIC PCS7 (All versions V8.1 and earlier), SIMATIC WinCC (All versions < V7.4 SP1), SIMATIC WinCC Runtime Professional (All versions < V14 SP1), SIMATIC NET PC Software, and SIMATIC IT Production Suite. By sending specially crafted packets to the OPC Discovery Server at port 4840/tcp, an attacker might cause the system to access various resources chosen by the attacker.

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.

The login implementation in the Web Navigator in Siemens WinCC before 7.2 Update 1, as used in SIMATIC PCS7 8.0 SP1 and earlier and other products, has a hardcoded account, which makes it easier for remote attackers to obtain access via an unspecified request.

SQL injection vulnerability in the login screen in the Web Navigator in Siemens WinCC before 7.2 Update 1, as used in SIMATIC PCS7 8.0 SP1 and earlier and other products, allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

SQL injection vulnerability in WebNavigator in Siemens WinCC 7.0 SP3 and earlier, as used in SIMATIC PCS7 and other products, allows remote attackers to execute arbitrary SQL commands via a crafted SOAP message.
