TITLE

Siemens WinCC Directory Traversal Vulnerability

Trust: 1.4

sources: IVD: c4c1d040-2353-11e6-abef-000c29c66e3d // CNVD: CNVD-2012-3213 // CNNVD: CNNVD-201206-086

DESCRIPTION

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. WinCC flexible is a human-machine interface for use in some machine or process applications. An attacker can exploit the vulnerability to read arbitrary files. Siemens SIMATIC WinCC Flexible is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, execute arbitrary code in the context of the affected application, read arbitrary files on the system, redirect users to a potentially malicious site, access or modify data of an XML document, or cause denial-of-service conditions; other attacks may also be possible. The vulnerability is caused due to an input sanitisation error within the DiagAgent web server and can be exploited to cause a buffer overflow and crash the DiagAgent. Successful exploitation requires the DiagAgent web server to be enabled (disabled by default). ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

This can be exploited to manipulate XPath queries by injecting arbitrary XPath code and e.g. read or write certain system settings. 2) Certain input passed via a filename to two unspecified web applications is not properly verified before being used to display files. This can be exploited to disclose the contents of arbitrary files via directory traversal sequences. 3) Certain input passed to two unspecified web applications is not properly sanitised before being returned to the user. 4) Certain input is not properly verified before being used to redirect users. This can be exploited to redirect a user to an arbitrary website e.g. when a user clicks a specially crafted link to the affected script hosted on a trusted domain. The weakness and the vulnerabilities are reported in version 7.0 SP3. SOLUTION: Apply "Update 2" (please see the vendor's advisory for details). PROVIDED AND/OR DISCOVERED BY: 1-3) The vendor credits Gleb Gritsai, Alexander Zaitsev, Sergey Scherbel, Yuri Goltsev, Dmitry Serebryannikov, Sergey Bobrov, Denis Baranov, and Andrey Medov, Positive Technologies. 4) Reported by the vendor.
