Detailsinfo

A vulnerability, which was classified as critical, has been found in Siemens SIMATIC HMI panel (SCADA Software). Affected by this issue is some unknown functionality of the file miniweb.exe. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Impacted is confidentiality. CVE summarizes:

Directory traversal vulnerability in miniweb.exe 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 read arbitrary files via a ..%5c (dot dot backslash) in a URI.

The weakness was shared 02/03/2012 by Luigi Auriemma (Website). The advisory is shared for download at us-cert.gov. This vulnerability is handled as CVE-2011-4878 since 12/21/2011. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1006.

A public exploit has been developed by Luigi Auriemma in Python and been published even before and not after the advisory. The exploit is available at securityfocus.com.
