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