Cisco WebVPN "dnserror.html" and "connecterror.html" Cross Site Scripting Issue


Description   A vulnerability has been identified in Cisco WebVPN, which could be exploited by attackers to execute arbitrary scripting code. This flaw is due to input validation errors in the clientless mode that does not validate a malformed URL before being displayed via the "dnserror.html" and "connecterror.html" pages, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.
