Toxin
Toxin Labs' internal operations dashboard. They've added security layers to their file browser — are they enough?
The Scenario
After a previous incident, Toxin Labs hardened their internal file viewer with input filters and request inspection. They're confident it's locked down. Prove them wrong.
Challenge Intel
Synopsis
A hard local file inclusion lab where a hardened file viewer invites you to bypass its defences.
What It Is
Toxin Labs responded to a previous incident by bolting filters and request inspection onto their internal file-browsing tool. The team believes they've closed the door, but their hardening operates at a shallower layer than the underlying loader. Expect a realistic LFI workout in bypassing layered defences rather than finding the initial flaw.
Who It's For
Advanced testers who enjoy defeating filters and WAF-style defences on top of a known vulnerability class.
Skills You'll Practice
- Advanced LFI under active filtering
- Filter and request-inspection bypass
- Encoding and normalization trickery
- Probing layered defences for gaps
- Mapping the true boundary of a protective layer
What You'll Gain
- Real experience defeating defence-in-depth around LFI
- A library of bypass ideas grounded in a concrete target
- Stronger judgement about when 'hardened' really means hardened
- A challenging capstone for your path-traversal practice
