CRITICAL:
Less critical
IMPACT:
Cross Site Scripting
WHERE:

SOFTWARE:
Moodle 1.7.x

DESCRIPTION:
MustLive has discovered a vulnerability in Moodle, which can be
exploited by malicious people to conduct cross-site scripting
attacks.
Input passed to the "search" parameter in user/index.php (when "id"
is set to a valid course) is not properly sanitised before being
returned to the user. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
site.
Successful exploitation requires that the target user is using
Internet Explorer. In the default configuration of Moodle, it also
requires that the target user has valid user credentials.
The vulnerability is confirmed in version 1.8.1 and reported in
version 1.7.1. Other versions may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
