How the CVE Works
CVE-2025-24071 is a critical spoofing vulnerability in Windows File Explorer that allows unauthorized attackers to expose sensitive information over a network. The flaw arises due to improper handling of file metadata, enabling malicious actors to craft deceptive file properties (e.g., fake icons, names, or locations). When a user interacts with the spoofed file, the attacker can redirect actions to a malicious network share or execute arbitrary code. The vulnerability leverages weak SMB (Server Message Block) protocol validation, allowing attackers to impersonate legitimate resources.
