Due to a vulnerability in Dell TrueMobile's systray applet, the applet's inability to drop SYSTEM privileges when it tries to show the help file, a local attacker can gain administrative/SYSTEM privileges.
Vulnerable Systems:
* Windows XP and Dell TrueMobile 1300 WLAN Mini-PCI Card Utility Tray Applet version 3.10.39.0
The SYSTEM rights are not dropped when accessing the Dell TrueMobile Wireless Help from the systray applet. By right clicking and choosing Help -> Help Files and then from the help; Jump to URL C:\WINDOWS\SYSTEM32\CMD.EXE, gives you SYSTEM privileges. You can also gain SYSTEM privileges by right clicking and choosing Help -> About. By clicking on a link, Internet Explorer will start with SYSTEM privileges. Programs started from the web browser do not get their privileges dropped.
