I Broke an FTP Server with Just a Username 😳 (Day 7 RCE Demo)

🔗GitHub Lab Setup: https://github.com/amalpvatayam67/day... ⚡ USER → CMD parsing → RCE — WingFTP-style (Docker Lab Demo) ⚡ In this video I demo a WingFTP-style parsing bug in a tiny FTP-like server running in Docker. The lab shows how improper parsing of protocol input (the USER line) can lead to command execution and allow access to local files — demonstrated safely inside an isolated container. 🔍 What you’ll learn Why malformed protocol parsing can be dangerous How untrusted input can turn into server-side command execution in the worst cases Realistic impacts: reading local files, escalating access, and potential lateral movement Practical mitigations and hardening steps to prevent this class of bug 🧩 Lab notes This repo simulates the class of parsing bugs seen in some FTP/management services — it is not the upstream Wing FTP code, it’s a minimal educational reproduction. Service listens on port 2121 inside the lab. 🛡️ Mitigation (quick) Patch vendor fixes or remove vulnerable parsing code. Run services with least privilege and avoid executing parsed input. Restrict access to management/FTP ports (firewall, VPN). Add input validation & canonical protocol parsing; monitor for anomalous USER commands. Implement strong logging and endpoint telemetry to detect suspicious activity. ⚠️ Disclaimer This video is for educational purposes only. Everything shown runs in an isolated Docker lab on localhost. Do NOT use these techniques on real/production systems or systems you don’t own. Unauthorized access is illegal. Hack responsibly. 👉 Try it yourself: clone the repo and run the lab locally to learn how the vulnerability behaves — focus on defensive understanding and mitigation. 👋 Hi, I’m Amal P Vatayam (online as Amal P).
