OWASP SKF XML External Entity Injection

A Python 2 Flask page that parses XML posted by the user with xml.dom.pulldom and renders the expanded <items> element back.

Objective

Declare an external entity in the XML you submit to read a local file from the server (XML external entity injection).

The brief for this lab lives in its repository.

Submit evidenceSecret

Launch the lab

Open it in the Cyber CTF launcher, or run it yourself with Docker Compose.

Open in the launcher Source code

›Run it manually

$git clone https://github.com/CyberCTF/skf-xxe && cd skf-xxe && docker compose up -d

Without the launcher, the lab uses its public development evidence: great for practice, but it won't complete the lab.
