Case Study
Finding an Authorization Weakness Before It Became a Problem
Conducted an authorization review of a production SaaS application and identified inconsistent route protection affecting role-based navigation. Worked with the development team to validate the finding and verify the remediation.
| Method | Manual Burp Suite Review |
|---|---|
| Finding | Authorization Weakness |
| Severity | Low to Medium |
| Status | Remediated |
| Time to Fix | Same Day |
| Outcome | Route-level authorization implemented |
The Challenge
During a security review of the platform, one detail stood out: a staff user couldn't see the Staff or Offices sections in the application's navigation.
That raised a simple question: was the functionality actually protected, or was it only hidden from the interface? Many authorization issues happen because developers protect the UI but forget that users can interact with routes directly.
The Assessment
Using Burp Suite, the application was tested by requesting protected routes directly instead of navigating through the interface. The pages still responded successfully, indicating that route-level authorization wasn't being consistently enforced.
While the backend remained the final authority for sensitive operations, users could still access page shells that weren't intended for their role.
The Solution
After the finding was reported, the application was updated to include:
- Route-level authorization
- Shared authorization rules between the frontend and middleware
- Automatic redirects for unauthorized users back to the dashboard
- Backend authorization remaining the final security layer
The issue was fixed shortly after disclosure.
Impact
Although no sensitive data was exposed, strengthening authorization at multiple layers improved the application's security posture by:
- Preventing unauthorized navigation
- Reducing information disclosure
- Creating consistent access control across the application
- Improving the overall user experience for unauthorized requests
Technologies Used
Key Takeaway
Security isn't just about encrypting data or preventing SQL injection. Sometimes the biggest improvements come from asking a simple question: "What happens if I skip the UI?"
