CVE-2024-38217 is a Windows Mark of the Web security feature bypass known as LNK Stomping. Specially crafted Windows shortcuts contain trailing characters in their targets that Windows removes during shortcut normalization. Windows Explorer saves the modified shortcut back to disk, removing its Mark of the Web designation in the process. This permits malicious programs to bypass origin-dependent security checks and warnings, including SmartScreen and Smart App Control protections. The vulnerability was actively exploited before Microsoft released a fix in September 2024; historical samples suggest abuse dating back to 2018.

A Microsoft Windows LNK-related zero-day flaw mentioned only in related coverage, not discussed as part of the WSUS incident.
A Windows Mark of the Web security feature bypass vulnerability affecting all versions of Windows including Windows 11 24H2; Microsoft reports active exploitation in the wild.
A Windows Mark of the Web bypass involving shortcut (.lnk) files. When a shortcut points to an executable path ending in an extra character, such as a period, Windows normalizes the path and rewrites the shortcut, removing MoTW. This bypasses associated SmartScreen and Smart App Control checks. The article reports exploitation over several years.
A Windows vulnerability exploited in LNK stomping attacks to bypass Mark of the Web protections. Mentioned as another actively exploited zero-day patched during September 2024 Patch Tuesday, without an explicit connection to the Void Banshee campaign.
