title: SonicWALL Global Security Client Local Privilege
program: SonicWALL Global Security Client
vulnerable version: 22.214.171.124 and possibly other versions
found: October 2006

The SonicWALL Global Security Client offers IT professionals the
capability to manage a mobile user’s online access, based upon corporate
policies, in order to ensure optimal security of the network and
maximize network resources. Instant messaging, high-risk Web sites and
network file access can all be allowed or disallowed as security and
productivity concerns dictate.
Local exploitation of a design error in SonicWALLs Global Security
Client could allow attackers to obtain increased privileges.
The problem specifically exists because SYSTEM privileges are not
dropped when accessing the GSC properties from the System Tray applet.
The vulnerability can be exploited by right-clicking the System Tray
icon, choosing "Log", right click "Event Viewer", "Open Log File...".
The opened file selected can be abused by navigating to C:\WINDOWS
\SYSTEM32\, right-clicking cmd.exe, then selecting "Open"; doing so
spawns a command shell with SYSTEM privileges.
Proof of concept:
This vulnerability can be exploited without any special exploit code.
