Open-source tool: Detect & fix Linux cron job privilege escalation (LPE)

After several months of research and lab testing, I’m releasing a complete guide + scripts to detect and fix privilege escalation via misconfigured cron jobs on Linux.

🚀 Key features:

  • Automated audit of cron jobs for security issues
  • Exploitation examples
  • Hardening tips
  • Open-source scripts

💡 Example: root shell on a cloud VM through a simple cron misconfiguration (see repo for details).

For sysadmins, SecOps, pentesters, or anyone passionate about Linux security.

👉 GitHub repo: https://github.com/privlabs/lpe-cron-misconfig-2025

Feel free to test, comment, or contribute! Would love your feedback or stories of similar issues you’ve found.
