Symantec AntiVirus 9 Corporate Edition Local Privilege Escalation
iDEFENSE Security Advisory 08.29.05
August 29, 2005
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:
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.
Successful exploitation allows a local attacker to execute arbitrary
commands as the System Administrator user.
iDEFENSE has confirmed this vulnerability exists in version 220.127.116.110
of Norton Antivirus Corporate Edition for Windows with all current
updates applied. This is a re-appearance of an old bug that was
reportedly fixed in versions 7.5.1 Build 62 and later, and version
7.6.1 Build 35a.
iDEFENSE is currently unaware of any workaround for this issue.
