Technical details
This vulnerability is a link-following (TOCTOU-style) flaw in Windows NTFS where improper validation before file access allows authorized local attackers to manipulate symbolic links or junctions. The attacker must have local file system access and appropriate permissions to exploit this. By creating or controlling symlinks, an attacker can redirect file operations to unintended locations, achieving local file tampering. The vulnerability requires local access and existing authorization, limiting the attack surface but enabling privilege escalation or data manipulation scenarios. A patch from Microsoft is expected to address the improper resolution logic.
