Description · NVD
STProcessMonitor 11.11.4.0, part of the Safetica Application suite, allows an admin-privileged user to send crafted IOCTL requests to terminate processes that are protected through a third-party implementation. This is caused by insufficient caller validation in the driver's IOCTL handler, enabling unauthorized processes to perform those actions in kernel space. Successful exploitation can lead to denial of service by disrupting critical third-party services or applications. Unauthorized processes load the driver and send a crafted IOCTL request (0xB822200C) to terminate processes protected by a third-party implementation. This action exploits insufficient caller validation in the driver's IOCTL handler, allowing unauthorized processes to perform termination operations in kernel space. Successful exploitation can lead to denial of service by disrupting critical third-party services or applications.
