| Description | Version: Webcam for Remote Desktop 2.8.42, ftwebcam.sys x.x.x.x, DoS
https://www.fabulatech.com/webcam-for-remote-desktop.html
Impact: Denial of Service
Description: From IoControlCode 0x222010 and 0x222018, a normal user can cause a null pointer dereference due to the lack of validating the return value of ExAllocatePoolWithTag, which leads to DoS.
Reproduce: In the attached file DoS1.zip, there are DoS1.exe, DoS1.cpp, webcam-for-remote-desktop-server-64bit.msi, and ftwebcam.sys. DoS1.exe is the PoC to cause BSOD where webcam-for-remote-desktop-server-64bit.msi contains the vulnerable driver ftwebcam.sys installed, and DoS1.cpp is the source code of DoS1.exe. To reproduce the issue, install webcam-for-remote-desktop-server-64bit.msi and execute DoS1.exe. It is expected that the system will crash (BSOD) once DoS1.exe is executed. Password for attachment: DoS1
