Overview

Affected versions of AntiXSS are vulnerable to Cross-site Scripting (XSS).

The Microsoft Anti-Cross Site Scripting (AntiXSS) Library 3.x and 4.0 does not properly evaluate characters after the detection of a Cascading Style Sheets (CSS) escaped character, which allows remote attackers to conduct cross-site scripting (XSS) attacks via HTML input, aka "AntiXSS Library Bypass Vulnerability."
