CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data

WHERE:
>From remote

SOFTWARE:
Moodle 1.2.x
http://secunia.com/product/3445/
Moodle 1.3.x
http://secunia.com/product/3675/

DESCRIPTION:
rgod has discovered some vulnerabilities in Moodle, which can be
exploited by malicious people to conduct cross-site scripting and SQL
injection attacks.

1) Input passed to the "id" parameter in "category.php" and
"info.php", and the "user" parameter in "plot.php" isn't properly
sanitised before being used in a SQL query. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

2) Input passed to the "jump" parameter in "jumpto.php" isn't
properly verified and sanitised before being returned to the user.
This can be exploited to execute arbitrary Javascript code in a
user's browser session in context of an affected site via the
"javascript:" URI handler.

The vulnerabilities have been confirmed in version 1.5.2. Other
versions may also be affected.

SOLUTION:
The vulnerabilities have reportedly been fixed in version 1.6dev.
