Technical details
The vulnerability exists in the IRP_MJ_DEVICE_CONTROL handler of the IUForceDelete.sys driver, which improperly manages privilege validation when processing IOCTL requests. An attacker with local system access can craft malicious IOCTL commands to bypass privilege checks and execute arbitrary operations with elevated permissions. The attack requires local access and does not involve remote network exploitation. The vendor was contacted prior to disclosure but did not provide a response or patch.
