Local Linux system check for privilege escalation 

In this recipe, we will use a Python script to check the system for vulnerabilities that could lead to privilege escalation.

Getting ready

Let's ensure the following prerequisites:

• Your Metasploitable machine is connected to the NAT network (remove it immediately after this lab)
• Your Metasploitable machine is powered up

How to do it...

In this recipe we will try and discover a vulnerability that will allow us to escalate privileges in linux:

1. Log in to the Metasploitable machine with the username msfadmin and password msfadmin.

2. From the terminal prompt of the Metasploitable machine, run the following commands:

cd <enter>
wget http://www.securitysift.com/download/linuxprivchecker.py <enter>
python ./linuxprivchecker.py >> vulns.txt <enter>
tail --lines=50 vulns.txt |more <enter>

3. You can now scroll through a list of vulnerabilities that can be used against this machine to provide privilege escalation:
