Signature Detail

HTTP: Microsoft .NET Form Authentication Insecure Redirect

This signature detects attempts to exploit a known flaw in Microsoft's .NET framework. The vulnerability is due to insufficient validation of a URL. A remote, unauthenticated attacker could exploit this vulnerability by enticing a target user to visit a URL. Exploitation could lead to information disclosure.

Extended Description

Microsoft .NET Framework is prone to a URI open-redirection vulnerability because it fails to properly sanitize user-supplied input. Successful exploits will redirect a user to a potentially malicious site; this could aid in phishing attacks.
