Cross-site request forgery (CSRF) vulnerability in WebNavigator in Siemens WinCC 7.0 SP3 and earlier, as used in SIMATIC PCS7 and other products, allows remote attackers to hijack the authentication of arbitrary users for requests that modify data or cause a denial of service.

WebNavigator in Siemens WinCC 7.0 SP3 and earlier, as used in SIMATIC PCS7 and other products, stores sensitive information under the web root with insufficient access control, which allows remote attackers to read a (1) log file or (2) configuration file via a direct request.

The XPath functionality in unspecified web applications in Siemens WinCC 7.0 SP3 before Update 2 does not properly handle special characters in parameters, which allows remote authenticated users to read or modify settings via a crafted URL, related to an "XML injection" attack.

Buffer overflow in the DiagAgent web server in Siemens WinCC 7.0 SP3 through Update 2 allows remote attackers to cause a denial of service (agent outage) via crafted input.

Open redirect vulnerability in an unspecified web application in Siemens WinCC 7.0 SP3 before Update 2 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in a GET request.

Multiple cross-site scripting (XSS) vulnerabilities in unspecified web applications in Siemens WinCC 7.0 SP3 before Update 2 allow remote attackers to inject arbitrary web script or HTML via vectors involving special characters in parameters.

Multiple directory traversal vulnerabilities in Siemens WinCC 7.0 SP3 before Update 2 allow remote authenticated users to read arbitrary files via a crafted parameter in a URL.

Cross-site scripting (XSS) vulnerability in the HMI web server in Siemens WinCC flexible 2004, 2005, 2007, and 2008 before SP3; WinCC V11 (aka TIA portal) before SP2 Update 1; the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, a different vulnerability than CVE-2011-4510.

Stack-based buffer overflow in HmiLoad in the runtime loader in Siemens WinCC flexible 2004, 2005, 2007, and 2008; WinCC V11 (aka TIA portal); the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime, when Transfer Mode is enabled, allows remote attackers to execute arbitrary code via vectors related to Unicode strings.

HmiLoad in the runtime loader in Siemens WinCC flexible 2004, 2005, 2007, and 2008; WinCC V11 (aka TIA portal); the TP, OP, MP, Comfort Panels, and Mobile Panels SIMATIC HMI panels; WinCC V11 Runtime Advanced; and WinCC flexible Runtime, when Transfer Mode is enabled, allows remote attackers to cause a denial of service (application crash) by sending crafted data over TCP.
