If privileges or limit privileges are specified with the command it will override any default values specified in sudoers. A privilege set is a comma-separated list of privilege names.

Local privilege escalation is useful on any system that a hacker may compromise; the system account allows for several other things that aren’t normally possible (like resetting the administrator password). (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". privilege escalation attacks; however, they often lack the knowledge, skill, and resources to effectively safeguard their systems against such threats. This paper will examine Linux privilege escalation techniques used throughout 2016 in detail, highlighting how these techniques work and how adversaries are using them.
