Enumeration is the key.
(Linux) privilege escalation is all about:
Collect - Enumeration, more enumeration and some more enumeration.
Process - Sort through data, analyse and prioritisation.
Search - Know what to search for and where to find the exploit code.
Adapt - Customize the exploit, so it fits. Not every exploit work for every system "out of the box".
Try - Get ready for (lots of) trial and error.

 Operating System
What's the distribution type? What version?

INITIAL ACCESS
-------------------------------------

$ Drive-by Compromise
A drive-by compromise is when an adversary gains access to a system through a user visiting a website over the normal course of browsing.
Multiple ways of delivering exploit code to a browser exist, including:
    > A legitimate website injected with JavaScript, iFrames, XSS.
    > Malicious ads
    > Built-in web application interfaces (e.g. forum posts, comments, and other user controllable web content)
