Unquoted service paths could allow local Microsoft Windows operating system users to escalate their privileges if the affected products are not installed under their default path ("C:\Program Files\*" or the localized equivalent).

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 read arbitrary files via crafted packets.

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 Project administration application in Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, has a hardcoded encryption key, which allows remote attackers to obtain sensitive information by extracting this key from another product installation and then employing this key during the sniffing of network traffic on TCP port 1030.

Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, allows local users to gain privileges by leveraging weak system-object access control.

The database server in Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, allows remote authenticated users to gain privileges via a request to TCP port 1433.

The WebNavigator server in Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, allows remote authenticated users to gain privileges via a (1) HTTP or (2) HTTPS request.

The WebNavigator server in Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, allows remote attackers to obtain sensitive information via an HTTP request.

The Web Navigator in Siemens WinCC before 7.2 Update 1, as used in SIMATIC PCS7 8.0 SP1 and earlier and other products, exhibits different behavior for NetBIOS user names depending on whether the user account exists, which allows remote authenticated users to enumerate account names via crafted URL parameters.

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.

Directory traversal vulnerability in the web server in Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, allows remote authenticated users to read arbitrary files via vectors involving a query for a pathname.

Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, does not properly represent WebNavigator credentials in a database, which makes it easier for remote authenticated users to obtain sensitive information via a SQL query.

The web server in Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, allows remote attackers to obtain sensitive information or cause a denial of service via a crafted project file.

Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, does not properly assign privileges for the database containing WebNavigator credentials, which allows remote authenticated users to obtain sensitive information via a SQL query.

Buffer overflow in CCEServer (aka the central communications component) in Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, allows remote attackers to cause a denial of service via a crafted packet.

Buffer overflow in the RegReader ActiveX control in Siemens WinCC before 7.2, as used in SIMATIC PCS7 before 8.0 SP1 and other products, allows remote attackers to execute arbitrary code via a long parameter.
