> Symantec Norton Internet Security 2006 COM Object Security ByPass
> iDefense Security Advisory 05.09.07
> May 09, 2007
> I. BACKGROUND
> Norton Internet Security 2006 is a comprehensive system security suite
> that offers protection from spyware, viruses, identity theft,
> spam, and
> malicious network traffic. More information can be found on
> the vendors
> site at the following URL.
> II. DESCRIPTION
> Remote exploitation of a design error vulnerability in an ActiveX
> control installed by Symantec Norton Internet Security 2006
> could allow
> for the execution of arbitrary code.
> Norton Internet Security 2006 installs the following ActiveX control
> which is registered as safe for scripting:
> Progid: Symantec.Norton.AntiVirus.NAVOptions
> Clsid: 085ABFE2-D753-445C-8A2A-D4BD46CE0811
> File: C:\Program Files\Norton Internet Security\Norton
> Version: 220.127.116.11
> This control was designed for use in a application embedded
> web browser
> rather than a native Internet Explorer window. When this control is
> loaded in a standard browser window, it throws an error during
> initialization which leaves the browser in a defunct state. After the
> error dialog displays, other Symantec ActiveX Controls can be created
> without error even if they are not marked as safe for scripting. This
> can lead to remote code execution if the unsafe controls contain
> exploitable methods.
> III. ANALYSIS
> Exploitation allows malicious websites to load certain
> Symantec ActiveX
> Controls which were not designed or secured for web use.
> This condition can lead to the execution of arbitrary code in
> where unsafe controls contain exploitable vulnerabilities.
> IV. DETECTION
> iDefense confirmed the existence of this vulnerability within version
> 18.104.22.168 of NavOpts.dll as distributed with Norton Internet Security
> 2006. Prior versions are suspected to be vulnerable.
> V. WORKAROUND
> Setting the kill-bit for the ActiveX control will prevent
> this component
> from loading in Internet Explorer. Although this will prevent
> exploitation, it may also negatively impact the functionality of the
