Symantec Internet Security 2008 ActiveDataInfo.LaunchProcess Design Error Vulnerability

BACKGROUND

DESCRIPTION

Remote exploitation of a design error in an ActiveX control installed with Symantec Norton Internet Security 2008 could allow for the execution of arbitrary code.

Norton Internet Security 2008 installs the following ActiveX control which is registered as safe for scripting:

 Progid: SymAData.ActiveDataInfo.1 Clsid: 3451DEDE-631F-421c-8127-FD793AFC6CC8 File: C:PROGRA~1COMMON~1SYMANT~1SUPPOR~1SymAData.dll Version: 2.7.0.1 

This control contains functionality designed to allow Symantec to remotely execute programs on the target machine.

ANALYSIS

Exploitation allows attackers to execute arbitrary code with the privileges of the currently logged in user. In order for exploitation to occur, an attacker would have to lure a vulnerable user to a malicious web site.

While this control is marked as safe for scripting, the control has been designed so that it can only be run from the "symantec.com" domain. In practice this requirement can be bypassed through the use of any Cross Site Scripting (XSS) vulnerabilities in the Symantec domain. Exploitation could also occur through the use of DNS poisoning attacks.

DETECTION

iDefense confirmed that this vulnerability exists in version 2.7.0.1 of the control that is installed with the 2008 version of Norton Internet Security. Other versions may also be available.

WORKAROUND

Setting the kill-bit for this control will prevent it from being loaded within Internet Explorer. However, doing so will prevent legitimate use of the control.

VENDOR RESPONSE

Symantec has addressed this vulnerability by releasing updates. For more information, refer to their advisory at the following URL.
