Symantec AntiVirus 9 Corporate Edition Local Privilege Escalation Vulnerability

iDEFENSE Security Advisory 08.29.05 www.idefense.com/application/poi/display?id=298&type=vulnerabilities August 29, 2005

I. BACKGROUND

Symantec AntiVirus 9 Corporate Edition is an enterprise quality Anti-Virus solution for the Windows platform.

More information can be found at the following location:

http://enterprisesecurity.symantec.com/products/products.cfm?ProductID=1 55

II. DESCRIPTION

Local exploitation of a design error in the Symantec AntiVirus 9 Corporate Edition may allow a user to gain elevated privileges. Exploitation can occur when a user chooses the right click "Scan for viruses" option. The Symantec scan file interface allows the user to launch a help window through the use of a toolbar icon. If the user then right clicks the help window title bar they can choose the "Jump to URL" menu option, which will then allow them to browse the local file system and execute files as the SYSTEM user.

This vulnerability is a re-appearance of an old bug formerly found in the Symantec 7.x series virus scan product.
