Fix your BTR3 4.5.0 Metasploit After Update Guide

After Kali went official, BTR3 was kinda abandoned and I got to see alot of pissed off people online looking to fix their Backtrack 5 R3's metasploit. Due to work's requirement, I start scouring for help all over the interwebs and found a few useful instructions. Here's a post to summarize and consolidate all the help I've gotten by nice folks on the internet. Hope this step-by-step guide will un-break your metasploit on your BTR3. It'll not take more than 15mins. Have fun!

Main idea: Upgrade your BT's Ruby from 1.9.2 to 1.9.3

Error: You may have encountered the error when trying to get Factory Girl 4.2.0 to work while perform 'bundle install' as requested by sir Metasploit himself. 

Summary of fix:

- Install 1.9.3

- Fresh install of metasploit using 'git clone' (avoid the SVN version from now on)

- And as usual, link and unbreak stuffs.

Limitation of fix:

Bad news, BTR3 doesn’t have Ruby1.9.3 in the repository so RVM is being used to install the version.

Need to do ‘/bin/bash –login’ whenever ./msfconsole is to be used.

Steps to retrieve the working version of metasploit

1. # cd /opt/

2. # rm -rf metasploit

3. # git clone --depth=1 git://github.com/rapid7/metasploit-framework metasploit

Let's open a new tab by pressing ctrl-shift-t.

Steps to install Ruby 1.9.3

1. # bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

2. # source /etc/profile.d/rvm.sh

3. # rvm -v

Let's fix up some libraries we need:

4. # package in zlib openssl libxslt libxml2; do rvm pkg install $package; done

5. # rvm install 1.9.3

You'll get error saying you need certain dependencies. 

6. # apt-get install <dependency 1> <dependency 2> ...

And of course, libssl-dev will still be screwed coz' current repository doesn't contain the right one. Let's add one to our /etc/apt/sources.list

7. # echo >> deb http://security.ubuntu.com/ubuntu lucid-security main /etc/apt/sources.list

8. # apt-get install libssl-dev 

Let's proceed to install our dear ruby 1.9.3 runtime:

9. # rvm install 1.9.3

So done? Let's switched to it. Current version will be 1.9.2-dev, so we gotta use our new shiny ruby 1.9.3.

10. # rvm 1.9.3 --default 

You'll see an error. So you'll need to do a login shell coz the current one just won't do.

11. # /bin/bash --login

12. # rvm 1.9.3 --default

13. # ruby -v

Now we have our 1.9.3. But something's still broken (yes of course, of course). Let's fix the pg.

14. # apt-get install libpq-dev

15. # gem install pg

Ok. Final moment of truth, let's proceed to the metasploit folder now!

16. # cd /opt/metasploit

17. # bundle install

*DEEP BREATH* Yes. Factory Girl 4.2.0 will install properly with Ruby 1.9.3 ;) And yes, you will be able to ./msfconsole

Long load time for ./msfconsole without any error means good news.

Congratulations! (and ba*ls to backtrack for not automating the update.)
