directory junction attack

A directory junction attack exploits symbolic links or directory junctions to redirect file system operations, often leading to privilege escalation or unauthorized access. On WindowsForum.com, discussions highlight how Microsoft's April 2025 cumulative update introduced an empty inetpub folder to patch CVE-2025-21204, a vulnerability that could be leveraged in directory junction attacks. The folder itself is not a threat but a security fix. Users and IT professionals examine the update's implications, including how directory junctions might be misused to bypass security controls or elevate privileges. The tag covers real-world examples of such attacks, mitigation strategies, and the role of Windows updates in addressing these vulnerabilities.
