| Описание | Version: Easy File Locker x.x.x.x, xlkfs.sys x.x.x.x, DoS
Impact: Denial of Service
Description: In MessageNotifyCallback, a normal user can send a large value by FilterConnectCommunicationPort to cause out of bound due to the lack of validating input buffer, which will lead to DoS or possibly have unspecified other impact.
Reproduce: In the attached file DoS.zip, there are DoS.exe, DoS.cpp, EFL2.2_Setup(x64).exe, and xlkfs.sys. DoS.exe is the PoC to cause BSOD where EFL2.2_Setup(x64).exe which contains the vulnerable driver xlkfs.sys is installed, and DoS.cpp is the source code of DoS.exe. To reproduce the issue, just install EFL2.2_Setup(x64).exe and execute DoS.exe. It is expected that the system will crash (BSOD) once DoS.exe is executed. Password for attachment (DoS.zip): DoS
