* Newer versions of Norton Internet Security do not include this control.
* Older versions of this control are suspected to be vulnerable. Other products utilizing this control should be considered vulnerable.
The ActiveX affected control can be identified by the ProgId of "SPRT.SmartIssue" or the CLSID of "01010e00-5e80-11d8-9e86-0007e96c65ae". This ActiveX control is marked safe for scripting as it is intended to be used in a web browser.
When installed with Norton Internet Security (NIS) 2006, the code responsible for implementing the control can be found in "C:\Program Files\Common Files\Symantec Shared\tgctlsi.dll".
Exploitation allows attackers to execute arbitrary code within the context of the current user.
In order to be successful, the attacker must persuade the victim into viewing a maliciously crafted web page. This can easily be accomplished by enticing them into clicking a link via e-mail, an instant messenger, or other means.
