The vulnerability is caused due to an error when processing the 0x7201C008 IOCTL and can be exploited to corrupt certain system data (e.g. filesystem table). Successful exploitation may allow execution of arbitrary code with SYSTEM privileges, but requires guessing the device filename, which is based on certain system information. The vulnerability is confirmed in version 1.0.15.15641. Other versions may also be affected. SOLUTION: Restrict access to trusted users only.
