SmartScreen Prompt Security Feature Bypass Vulnerability

Vulnerabilidad de omisión de la función de seguridad de solicitud de SmartScreen

This vulnerability allows remote attackers to bypass the SmartScreen security feature to execute arbitrary code on affected installations of Microsoft Windows. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of Internet Shortcut (.URL) files. The issue results from the lack of a security check on chained Internet Shortcut files. An attacker can leverage this vulnerability to execute code in the context of the current user.

Microsoft SmartScreen Prompt contains a security feature bypass vulnerability that allows an attacker to bypass the Mark of the Web (MotW) feature. This vulnerability can be chained with CVE-2023-38831 and CVE-2024-21412 to execute a malicious file.
