Arbitrary File Write via Directory Junction in WatchDog Anti-Virus Quarantine Restoration

Published Sep 20, 2026 · Updated Sep 21, 2026 · Assigned by watchdog

Description

Improper link resolution before file access in the quarantine restoration process of WatchDog Anti-Virus 1.8.640 on Windows allows local, low-privileged attackers to cause a quarantined file to be written to an arbitrary filesystem location by creating a directory junction at the original file path and persuading an administrator to restore the file. This may enable modification of protected files or SYSTEM-level code execution through DLL hijacking.
