# PostfixAdmin Setup Page Exposure Detection Module

  name: PostfixAdmin Setup Page Exposure
  author: sif
  severity: medium
  description: Detects a reachable PostfixAdmin setup.php that discloses hosting/environment checks and install state unauthenticated. Since PostfixAdmin 2.3 the setup password gate blocks remote superadmin creation without the configured setup_password, so this is an information-disclosure and unhardened-install signal rather than a direct authentication bypass.
