VERIFY ADVISORY:
http://secunia.com/advisories/21161/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Novell Client Firewall (NCF) 2.x
http://secunia.com/product/3122/

DESCRIPTION:
A vulnerability has been discovered in Novell Client Firewall, which
can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to the application windows running
with SYSTEM privileges and not properly restricting users from
running arbitrary programs. This can be exploited to execute
arbitrary commands with SYSTEM privileges by e.g. crafting a batch
file executing cmd.exe and then move another file over this file
inside Explorer via the "Save Configuration As…" functionality or
similar.

The vulnerability has been confirmed in version 2.0 Build 0727. Other
versions may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY:
Reported by H. Wiedemann in Outpost Firewall, which Novell Client
Firewall is based on.
