Exploitation Summary

EIP tracks 1 public exploit for CVE-2018-16713. PoCs published by DownWithUp.

AI-analyzed exploit summary This PoC exploits CVE-2018-16713 by leveraging the IOBit WinRing0 driver to read the MSR_LSTAR register, demonstrating arbitrary MSR read access. It allocates executable memory regions and uses DeviceIoControl to interact with the vulnerable driver.

Description

IObit Advanced SystemCare, which includes Monitor_win10_x64.sys or Monitor_win7_x64.sys, 1.2.0.5 (and possibly earlier versions) allows a user to send an IOCTL (0x9C402084) with a buffer containing user defined content. The driver's subroutine will execute a rdmsr instruction with the user's buffer for input, and provide output from the instruction.
