2012-02-03 CVE-2011-4508 Improper Authentication vulnerability in Siemens products
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 generates predictable authentication tokens for cookies, which makes it easier for remote attackers to bypass authentication via a crafted cookie.
