Detection Engineering & Incident Response: CVE-2026-48282

Respond to a Adobe ColdFusion path-traversal-to-RCE compromise (CVE-2026-48282). Reconstruct the timeline from the access and server logs, see how traversal in a template parameter included an attacker .cfm and ran code, find the CFM web-shell persistence, engineer a detection rule for traversal, then contain, eradicate, update, verify and report.

The scenario

An internet-facing Adobe ColdFusion server (CVE-2026-48282 open) logged traversal in a template parameter, then a .cfm file appeared and a shell spawned. You are the responder. Classify it.

What you will do

  1. Open and classify the incident4 steps

    Open the incident · Read the alert · Read the ticket · Classify it

  2. Reconstruct the timeline3 steps

    Pull the attacker’s requests · Correlate the server log · What turned traversal into RCE?

  3. Impact and persistence3 steps

    Inspect the web shell · What persistence? · Record IOCs

  4. Engineer a detection rule4 steps

    Study the sample · Write a rule · Test and tune · Why not flag every dot?

  5. Contain, eradicate, verify4 steps

    Eradicate the web shell · Apply the update · Verify the host · Confirm detection holds

  6. Report2 steps

    Write the report · What config breaks the chain?

How this lab works

A real Linux-style console. Commands run against real files, so hashes, hex dumps and comparisons give real results.

A file browser where you can place evidence into the lab, either the file provided or one of your own.

Reset a single step, a whole task or the entire lab. The environment is rebuilt so you can try again cleanly.

Progress saves after every step. Close the tab and come back later; your files and answers are waiting.
