HackLab – VulnVoIP (“Harder” way in)

After finishing Vulnix I decided to take on VulnVoIP and try my hand with some phone system hacking! 🙂

The VM has some instructions on what to do other then get root:

VulnVoIP is based on a relatively old AsteriskNOW distribution and has a number of weaknesses. The aim is to locate VoIP users, crack their passwords and gain access to the Support account voicemail.


HackLab – VulnVoIP

So yes there is a REALLY easy way, and a harder way to do VulnVoIP. This is a quick and dirty write-up on the easy way…

root@kali:~# nmap -sU -p 5060

Starting Nmap 6.47 ( http://nmap.org ) at 2014-12-14 16:28 EST
Nmap scan report for
Host is up (0.00032s latency).
5060/udp open|filtered sip
MAC Address: 00:0C:29:D8:2E:59 (VMware)

Nmap done: 1 IP address (1 host up) scanned in 13.25 seconds

After that scan as well as running svmap…

HackLab – Vulnix

So I was poking around VulnHub for a new VM to work on and I came across Vulnix…  Here is how I got root!



Found ssh credentials.

Tried to login as User with the password “letmein”

We get access to user.

We also can see that this system is using rservices more specifically rlogin (We had a pretty good idea that this was the case with our original port scan showing port 513 being opened.)

Added wildcard + + to allow anybody to login with no password as user.
