🎯 Objective
This lab has an unprotected admin panel, but its location is unpredictable.
The hidden location is disclosed somewhere within the application.
Goal:
- Locate the admin panel.
- Use it to delete the user
carlos.
🧭 Strategy
When the admin panel isn’t at a predictable path (like /admin), look for indirect clues in the application.
Possible places to check:
- HTML source comments
- JavaScript files
- Error messages
- Internal links not visible in the UI
🔎 Analysis
1. Source Code Inspection
- Opened the page source (
Ctrl+U) - Searched for keywords like
href="/admin-*",<!-- hidden admin --> - Found references pointing to a hidden admin path.
2. Static File Review
- Checked linked resources (
.js,.css) - Looked for fetch calls or unused references revealing admin URLs.
3. Path Disclosure Patterns
- Looked for debug variables or console logs.
- Found
/admin-randomstringstyle path inside the HTML/JS.
4. Testing
- Navigated directly to the discovered path.
- Confirmed the hidden admin panel was accessible.
🚀 Discovery Process
- Checked
/robots.txt→ no useful data. - Inspected base HTML source → discovered clue referencing admin panel.
- Followed hidden link → located the real admin endpoint.
📝 Action Plan
- Locate hidden admin path (via HTML or JS).
- Navigate directly to that endpoint.
- Use the admin functionality to delete user carlos.
