TITLE

plural Siemens Product HMI Web Vulnerability to read data from arbitrary memory locations on the server

Trust: 0.8

sources: JVNDB: JVNDB-2012-001321

DESCRIPTION

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 does not properly handle URIs beginning with a 0xfa character, which allows remote attackers to read data from arbitrary memory locations or cause a denial of service (application crash) via a crafted POST request. Siemens SIMATIC is an automation software in a single engineering environment. A security vulnerability exists in the Siemens SIMATIC WinCC HMI web server. The HMI web server does not properly validate the HTTP request. The first byte in the URL is manipulated. Siemens SIMATIC WinCC is prone to an HTTP-header-injection issue, a directory-traversal issue, and an arbitrary memory-read access issue because the application fails to properly sanitize user-supplied input. A remote attacker can exploit these issues to gain elevated privileges, obtain sensitive information, or cause denial-of-service conditions. The vulnerability stems from the failure of miniweb.exe in the HMI web server to correctly handle URLs starting with the 0xfa character
