Linux Privilege Escalation
Linux Privilege Escalation
Purpose
Execute systematic privilege escalation assessments on Linux systems to identify and exploit misconfigurations, vulnerable services, and security weaknesses that allow elevation from low-privilege user access to root-level control. This skill enables comprehensive enumeration and exploitation of kernel vulnerabilities, sudo misconfigurations, SUID binaries, cron jobs, capabilities, PATH hijacking, and NFS weaknesses.
Inputs / Prerequisites
Required Access
- Low-privilege shell access to target Linux system
- Ability to execute commands (interactive or semi-interactive shell)
- Network access for reverse shell connections (if needed)
- Attacker machine for payload hosting and receiving shells
Technical Requirements
- Understanding of Linux filesystem permissions and ownership
- Familiarity with common Linux utilities and scripting
- Knowledge of kernel versions and associated vulnerabilities
- Basic understanding of compilation (gcc) for custom exploits
