A Hands-on Approach to Linux Privilege Escalation

This paper details multiple techniques for pentesters to escalate privileges and gain higher-level access in Linux systems.

Key Pointers:

  • Linux Privilege Escalation can be of many types. The types discussed in this document are:
    1. Privilege Escalation by kernel exploit
    2. Privilege Escalation by Password Mining
    3. Privilege Escalation by Sudo
    4. Privilege Escalation by File Permissions
    5. Privilege Escalation by Crontab
  • Setting up labs and performing the escalations.
  • Discussing the mitigations to prevent such privilege escalation exploits.
