Outpost Firewall Pro "open folder" privilege escalation
| outpost-openfolder-privilege-escalation (27848) |  High Risk |
Description:
Outpost Firewall Pro, Lavasoft Personal Firewall, and Novell Border Manager Novell Client Firewall could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability related to the "open folder" option. By stopping the explorer.exe process and restarting explorer.exe using the "open folder" option in the "Shared Components" window, a local attacker could open applications and execute arbitrary commands with SYSTEM level privileges.
Note: This vulnerability may be caused by an underlying issue in Microsoft Windows.

- CVE-2006-3697: Agnitum Outpost Firewall Pro 3.51.759.6511 (462), as used in (1) Lavasoft Personal Firewall 1.0.543.5722 (433) and (2) Novell BorderManager Novell Client Firewall 2.0, does not properly restrict user activities in application windows that run in a LocalSystem context, which allows local users to gain privileges and execute commands (a) via the open folder option when no instance of explorer.exe is running, possibly related to the ShellExecute API function; or (b) by overwriting a batch file through the Save Configuration As option. NOTE: this might be a vulnerability in Microsoft Windows and explorer.exe instead of the firewall.
