VERIFY ADVISORY:
http://secunia.com/advisories/17630/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
WHM AutoPilot 2.x
http://secunia.com/product/3747/

DESCRIPTION:
Agna Zilchi has discovered a vulnerability in WHM AutoPilot, which
can be exploited by malicious users to bypass certain security
restrictions.

The vulnerability is caused due to an input validation error in
"cancel_account.php" where the "c" parameter is not properly
verified. This can be exploited to request cancelling of hosts for
other accounts.

Successful exploitation requires that the administrator approves the
cancel request.

The vulnerability has been confirmed in version 2.5.30 and has also
been reported in version 2.5.20 and prior. Other versions may also be
affected.

SOLUTION:
Edit the source code to ensure that users can only perform requests
for their own accounts.
