# SambaHunter
It is a simple script to exploit RCE for Samba (CVE-2017-7494).

Now works with Python3. Many of the required Python2 libraries are deprecated (e.g. `commands`)

Added logging to show which shares are writeable. If 'Exploit Finished' appears but no shares are writeable, the exploit didn't work.

# Requirements
* sudo apt-get install smbclient
* pip install pysmbclient

# Usage
```
# python3 sambahunter.py -h
