CVE-2017-5930 is a vulnerability in the AliasHandler component of PostfixAdmin prior to version 3.0.2. It allows remote authenticated domain administrators to delete protected aliases by sending a crafted request to delete.php with the delete parameter. The vulnerability is due to a missing permission check, which fails to restrict domain admins from deleting aliases that should be protected.

This repository contains a single Metasploit auxiliary module targeting a vulnerability in Postfixadmin (CVE-2017-5930) affecting versions 2.91 to 3.0.1. The exploit allows an authenticated attacker to delete protected email aliases (such as postmaster@domain) and recreate them to redirect to an arbitrary email address, due to insufficient permission checks in the affected versions. The module is written in Ruby and leverages Metasploit's HTTP client mixin to interact with the target Postfixadmin instance. It requires valid admin credentials and the target's base URI. The module performs authentication, retrieves a CSRF token, deletes the specified alias, and then creates a new alias with the attacker's chosen redirection. The main endpoints targeted are /login.php, /list-virtual.php, /delete.php, and /edit.php on the Postfixadmin web interface. The exploit is operational and can be used to demonstrate the vulnerability or for post-exploitation to hijack important email aliases.
