Vulnerability Info

Version

Impact

Denial of Service

Description

From IoControlCode 0x9C40A0D8, 0x9C40A0DC, and 0x9C40A0E0, a normal user can call __outbyte, __outword, and __outdword respectively, which can lead to denial of service and other unknown impacts toward system e.g. UEFI attack.

Reproduce

In the attached file DoS2.zip, there are DoS2.exe, DoS2.cpp, DGSetup_Home_BZNR.exe, and mydrivers64.sys. DoS2.exe is the PoC to cause DoS where DGSetup_Home_BZNR.exe which contains the vulnerable driver mydrivers64.sys is installed, and DoS2.cpp is the source code of DoS2.exe. To reproduce the issue, install DGSetup_Home_BZNR.exe and execute DoS2.exe. It is expected that the system will restart once DoS2.exe is executed.
