CRITICAL:
Moderately critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Reamday Enterprises Magic Downloads 1.x
http://secunia.com/product/8082/

DESCRIPTION:
Aliaksandr Hartsuyeu has reported a vulnerability in Magic Downloads,
which can be exploited by malicious people to bypass certain security
restrictions.

The vulnerability is caused due to the $passwd, $admin_password,
$new_passwd, and $confirm_passwd" variables in "settings.php" not
being initialised before use. This can be exploited to change
settings (e.g. the administrator's password) within "config.php"
without requiring a valid logon.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been reported in version 1.1.3. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure the variables are properly
initialised.

PROVIDED AND/OR DISCOVERED BY:
