Jenkins CVE-2024-23897: From File Read to Full RCE on CI/CD Infrastructure
Learn to exploit Jenkins CVE-2024-23897 - a critical arbitrary file read vulnerability that leads to remote code execution. We'll demonstrate the complete attack chain: CLI enumeration, file disclosure via @ character exploitation, credential harvesting from Jenkins secrets, authentication bypass, and finally achieving RCE through the Script Console. This hands-on tutorial shows real penetration testing methodology against a vulnerable Jenkins 2.441 server. You'll see every command, every failed attempt, and every pivot decision that leads to full system compromise. Perfect for aspiring penetration testers who want to understand CI/CD security and how attackers target DevOps infrastructure. -- LAB SETUP -- Download the Docker Compose file from: https://github.com/terminalops/jenkins-cve... - Run: docker-compose up -d - Network: 10.0.2.0/24 (Docker bridge) - Kali Linux 2024.4+ with Java 11+ installed - Tools: nmap 7.94+, curl, wget, hashcat 6.2+, john 1.9+ Subscribe for weekly cybersecurity tutorials and hands-on penetration testing demos.
