These are exploits created to avoid the use of Metasploit. While studying for OSCP in the Offsec labs, VHL, Vulnhub, etc, I tried to find ways to limit my use of Metasploit and Meterpreter shells.
The first exploit (webdavrev.py) includes a php reverse shell for Windows found here
The second exploit (webdavbd.py) only puts a CMD backdoor on the target. This is useful if there are issues with getting a shell.
Do not use these or any of the above referenced exploits on any systems in which you do not have permission to do so.
