Did you know a poorly configured OAuth implementation can allow attackers to traverse your microservices and access highly sensitive internal data? Welcome back to another video on CyberSecurityTV! Today, we are diving deep into the OAuth Token Replay Attack across Microservices. We explore how attackers exploit path traversal vulnerabilities in reverse proxies (like NGINX or API Gateways) and reuse valid external OAuth tokens to authenticate against internal services. In this video, we break down: ✔️ The standard microservices topology and how API gateways route traffic. ✔️ How path traversal (../../) can bypass reverse proxy routing. ✔️ Why poor OAuth token validation allows external users to access internal microservices. ✔️ A hands-on demonstration using Burp Suite to intercept and replay OAuth tokens. ✔️ Privilege escalation: Moving from a public Express.js app to a restricted internal Django admin panel. ✔️ Best practices to secure your architecture: Implementing granular scopes and separating OAuth configurations. If you are a developer building microservices or a security researcher hunting for API logic flaws, this walkthrough is for you! ⏳ Video Chapters: 00:00 - Introduction to OAuth Token Replay Attack 00:26 - Understanding Microservices Topology & API Gateways 02:53 - How the Exploit Works (Path Traversal) 04:49 - Hands-on Lab Demo (oauthlab.securifyai.co) 05:40 - Intercepting Traffic with Burp Suite 06:40 - Traversing to Internal Django Services 07:42 - Replaying the OAuth Token to Gain Access 09:12 - How to Defend Against Token Replay Attacks 🔐 Secure your systems with Securify AI: https://securifyai.co/ 📖 Read our latest insights on the Blog: https://securifyai.co/blog/ Follow us for more Cyber Security updates!
