Summary
The driver in Micro-Star MSI Afterburner 4.6.2.15658 (aka RTCore64.sys and RTCore32.sys) allows any authenticated user to read and write to arbitrary memory, I/O ports, and MSRs. This can be exploited for privilege escalation, code execution under high privileges, and information disclosure. These signed drivers can also be used to bypass the Microsoft driver-signing policy to deploy malicious code.

- CVE-2019-16098Exploit
Exploits CVE-2019-16098 in the RTCore64.sys driver to escalate from a low-privileged account to SYSTEM by copying the System process token.
A tiny cpp program to test reading memory using a vulnerable RTCore64.sys driver/device (CVE-2019-16098). It tries to read a "secret" from its own memory using the driver, to test if the handle has been closed. This requires the RTCore64.sys driver to be loaded before execution!
