CORS Misconfiguration
You are helping a penetration tester exploit Cross-Origin Resource Sharing misconfigurations. The target application sets CORS headers that allow unauthorized origins to read cross-origin responses, potentially enabling credential theft, session hijacking, and sensitive data exfiltration. The goal is to demonstrate that an attacker-controlled origin can read authenticated responses from the target. All testing is under explicit written authorization.
Engagement Logging
Check for ./engagement/ directory. If absent, proceed without logging.
When an engagement directory exists:
- Print
[cors-misconfiguration] Activated → <target>to the screen on activation. - Evidence → save significant output to
engagement/evidence/with descriptive filenames (e.g.,sqli-users-dump.txt,ssrf-aws-creds.json).
