I am fuzzing around with Metasploitable and I ran a vulnerability scan with Nessus. I obviously got a bunch of critical vulnerabilities but I am clueless on what they are and how the exploit works. I did google it but their explanations are rather vague or just complex for me to understand (I am a stereotypical Script Kiddie, feel free to call me dumb). Can someone please tell me how and from where do I search more about the vulnerability and the exploit. Often the exploits are written in ruby (or languages that I am not fluent in, even the pro's aren't good in every language are they?) and I am just starting to learn it. (I am good in python though, I can understand most of the code). I am reading networking books along the lines and am good with Linux. Other than researching exploits and vulnerabilities can you explain how you got into and better with penetration testing? Thank you.
