ASP.NET Cross-Site Scripting Vulnerability

It is reported that ASP.NET is prone to various cross-site scripting attacks. These issues occur when ASP.NET converts Unicode characters ranging from U+ff00-U+ff60 to ASCII. Apparently, the application fails to properly validate Unicode characters allowing an attacker to craft a malicious link containing arbitrary HTML or script code to be executed in a user's browser. This can facilitate theft of cookie-based credentials and other attacks.

Mitigation:

Input validation should be used to ensure that user-supplied data is properly sanitized before being used in the application.
