How I Solved a Server-Side Template Injection Challenge (picoCTF Write-up)

Image descriptionHey folks ๐Ÿ‘‹

I recently tackled a Server-Side Template Injection (SSTI) challenge from the picoCTF and decided to create a write-up and a video to help others learn from it.

This post is a beginner-friendly explanation of the process, covering:

  • How to identify SSTI vulnerabilities
  • Payload crafting
  • Exploitation strategy
  • Things I learned and tools I used

๐ŸŽฅ Video Walkthrough

๐Ÿ“บ Watch the video on YouTube

๐Ÿง  Full Write-up with Code and Notes

๐Ÿ“– Check out the GitHub repository


This is meant for beginners and students diving into web exploitation, bug bounty, and CTFs.
