| 説明 | Version: Twister Antivirus 8, ffsmon.sys 1.0.3.5866
http://www.filseclab.com/en-us/downloads.htm
Impact: Denial of Service
Description: From IoControlCode 0x220013 and 0x220017, a normal user can cause DoS due to the lack of validating SystemBuffer.
Reproduce: In the attached file DoS.zip, there are DoS.exe, DoS.cpp, twister8_setup.exe, and ffsmon.sys. DoS.exe is the PoC to cause BSOD where twister8_setup.exe which contains the vulnerable driver ffsmon.sys is installed, and DoS.cpp is the source code of DoS.exe. To reproduce the issue, just install twister8_setup.exe and execute DoS.exe. It is expected that the system will crash (BSOD) once DoS.exe is executed.
