Perform the activity

  1. Review the supplied training app architecture.
  2. Identify form inputs and database fields.
  3. Trace a user registration from form submission to stored record.
Workshop safety: Activities involving scanning, web vulnerabilities or security testing must be performed only on the assigned training target or intentionally vulnerable lab.
04 · CODE / COMMANDS

Read and understand the working example

Suggested stack:
HTML/CSS + PHP or Flask + MySQL/SQLite

This example is shown for guided learning. Real host/network execution is reserved for the isolated cyber-range stage.
