A PoC for Mhyprot2.sys vulnerable driver that allowing read/write memory in kernel/user via unprivileged user process.
What we can do with this CLI is as follows:
- Read/Write any kernel memory with privilege of kernel from usermode
- Read/Write any user memory with privilege of kernel from usermode
- Enumerate a number of modules by specific process id
- Get system uptime
- Enumerate threads in specific process, result in allows us to reading
PETHREAD
structure in the kernel directly from CLI as well. - Terminate specific process by process id with
ZwTerminateProcess
which called in the vulnerable driver context (ring-0). - All operations are executed as kernel level privilege (ring-0) by the vulnerable driver
Also:
- Administrator privilege only needed if the service is not yet running
- Therefore we can execute commands above as the normal user (w/o administrator privilege)
- Any version of Windows x64 that the driver works on
- Administrator privilege does not required if the service already running
Tested on:
- Windows10 x64 1903
- Windows7 x64 6.1
- Windows8.1 x64 6.3
