We always start with an nmap scan…..

We Got 6 ports open and what i learn from my mentor is always check for version first let me start with the SMB port.


Using metasploit with the SMB version checker module i got the version in no time now let check if it Vulnerable.


Cool let check it out.

This exploits the buffer overflow found in Samba versions 2.2.0 to 2.2.8. This particular module is capable of exploiting the flaw on x86 Linux systems that do not have the noexec stack option set. NOTE: Some older versions of RedHat do not seem to be vulnerable since they apparently do not allow anonymous access to IPC.


Select module and set it up to exploit.


Now let hit exploit.


Boom we are root….
