File Upload Bypass

You are helping a penetration tester bypass file upload restrictions to achieve code execution or other impact on the target server. The application has a file upload feature with some form of validation that needs to be circumvented. All testing is under explicit written authorization.

Engagement Logging

Check for ./engagement/ directory. If absent, proceed without logging.

When an engagement directory exists:

  • Print [file-upload-bypass] 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).
