Description

Internet Shortcut Files Security Feature Bypass Vulnerability

In plain language

AI Act now

CVE-2024-21412 is a Windows security bypass involving “internet shortcut” files, and if you run supported Microsoft Windows devices (Windows 10/11 and Windows Server listed), you should act now because attackers are already exploiting it in the wild.

What to do

  1. Update all affected Windows 10/11 and Windows Server systems to the latest available security fixes as soon as possible (ask your IT person to confirm installed patch status for CVE-2024-21412). 2) Until patched, restrict opening internet shortcut files from emails/messages and block unknown downloads where you can. 3) Check whether your organization has any unpatched machines in the affected version list and prioritize servers and user endpoints first.
