🔐 SUID Binary Privilege Escalation

SUID (Set User ID) binaries are executable files that run with the privileges of their owner rather than the user executing them. When misconfigured, these binaries become powerful vectors for privilege escalation attacks, allowing attackers to gain elevated access within systems.

🎯 What You'll Learn
  • ✓ SUID binary identification techniques
  • ✓ Command injection in privileged binaries
  • ✓ Privilege escalation methodologies
  • ✓ Linux file permission exploitation
  • ✓ System security assessment
🔍 Challenge Overview

You'll encounter a web application that provides access to a file reading utility. This utility has been configured with special permissions to access system files, but contains a critical vulnerability that can be exploited for privilege escalation.

Penetration Testing Context: SUID binary vulnerabilities are commonly discovered during privilege escalation phases of penetration tests, where attackers seek to elevate their access from standard user accounts to administrative privileges.
