Description:
Nomenumbra has discovered a vulnerability in X7 Chat, which can be exploited by malicious people to conduct script insertion attacks.
Input passed to the "avatar" parameter when setting the URL for a remote avatar image isn't properly verified before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data containing a reference to a URL with the "javascript:" URI handler is viewed with the Microsoft Internet Explorer browser.
The vulnerability has been confirmed in version 2.0.2. Other versions may also be affected.
Solution:
Update to version 2.0.4.
