Summary

Missing Authorization in the IOCTL handlers of the wsdkd.sys kernel drivers in Watchdog WatchDog Antivirus 1.8.640 (driver versions 1.3.0.0 and earlier) on Microsoft Windows allows local, low-privileged attackers to delete arbitrary files with SYSTEM privileges, bypassing NTFS access controls, via crafted IOCTL requests sent to the \Device\wsdk device.

Risk Assessment

A local, low-privileged attacker could delete arbitrary files with SYSTEM privileges, potentially disabling security products or destabilizing the operating system. This poses a serious threat to confidentiality, integrity, and availability.

Recommendation

Update WatchDog Antivirus to a patched version or a driver version newer than 1.3.0.0. Until then, consider restricting access to the \Device\wsdk device and monitoring for exploitation attempts.
