CRITICAL:
Highly critical

IMPACT:
Security Bypass, System access

WHERE:

SOFTWARE:
PMOS Help Desk 2.x

DESCRIPTION:
EgiX has discovered a vulnerability in PMOS Help Desk, which can be
exploited by malicious people to bypass certain security restrictions
and to compromise a vulnerable system.

The form.php script does not properly restrict access to logged-in
users and can be exploited with an HTTP client that does not follow
redirects. This can be exploited to e.g. execute arbitrary PHP code.

The vulnerability is confirmed in version 2.4. Other versions may
also be affected.

SOLUTION:
Implement proper checking of user credentials in form.php.

Use another product.
