CRITICAL:
Moderately critical
IMPACT:

WHERE:
>From remote

DESCRIPTION:
Thomas Pollet has discovered a vulnerability in PHPX, which can be
exploited by malicious people to conduct script insertion attacks.
Input passed via the "url" XCode tag when posting a message isn't
properly verified, 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 a malicious link with the
"JavaScript" URI handler is followed from a malicious message.
Example:
[url=javascript:[code]]text[/url]
The vulnerability has been confirmed in version 3.5.9. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
