4) Description of Vulnerability

Secunia Research has discovered a vulnerability in cPanel, which can
be exploited by malicious people to conduct script insertion attacks.

Input passed to the chat message field in the pre-installed
Entropy Chat script isn't properly sanitised before being used. This
can be exploited to inject arbitrary script code, which will be
executed in a user's browser session in context of an affected site
when the malicious user data is viewed with the
Microsoft Internet Explorer browser.

Example:
Send message <b style="width:expression([code])">text</b>
via http://[host]:2084/

The vulnerability has been confirmed in versions 10.2.0-R82 and
10.6.0-R137. Other versions may also be affected.

======================================================================
5) Solution

Edit the source code to ensure that input is properly sanitised.
