Squid is a caching web proxy. The target machine as described below is running squid proxy. The proxy is configured only to serve requests coming from a specific web browser ("Firefox"). A web portal is running on the target machine. This portal is reachable only via the proxy

Objective: You have to figure out a way to access the web portal and retrieve the flag!

Instructions: 

• This lab is dedicated to you! No other users are on this network :)
• Once you start the lab, you will have access to a root terminal of a Kali instance
• Your Kali has an interface with IP address 192.X.Y.Z. Run "ip addr" to know the values of X and Y.
• The Target machine should be located at the IP address 192.X.Y.3.
• Do not attack the gateway located at IP address 192.X.Y.1
• postgresql is not running by default so Metasploit may give you an error about this when starting

The solution for this lab can be found in the following manual: https://assets.ine.com/labs/ad-manuals/walkthrough-225.pdf
