Security readout for executives and security teams

This affects old ICQ Client 5.04 build 2321 and earlier. A remote attacker could inject web script through a banner that ICQ processed in the Windows My Computer zone using the Internet Explorer COM object. Business risk mainly concerns legacy desktops still running this client. Exposure is likely limited to endpoints with ICQ Client 5.04 build 2321 or earlier installed and able to receive or process banner content. Treat this as a legacy exposure cleanup item unless ICQ is still present in the environment. Prioritize confirmation through software inventory before allocating incident-response effort. Mitigation focus: Identify and remove ICQ Client 5.04 build 2321 or earlier from managed endpoints.; Check original vendor or trusted advisory guidance for fixed versions or supported removal guidance.; Restrict legacy instant messaging clients that embed Internet Explorer components..
