  1. Description
   
  Metasploit Pro, Express, Ultimate, and Community can encounter an issue of cross site request forgery (also known as one-click attack and is abbreviated as CSRF or XSRF), which is a type of malicious exploit of a website where unauthorized commands are transmitted from a user that the web application trusts. A CSRF attack attempts to exploit the trust that a specific website has in a user's browser.
   
  2. Proof of concept
   
  The MSF did not protect the logout form with csrf token, therefore i can logout any user by sending this url https://Metasploit-Server-IP:3790/logout
  Here's an attack vector:
  
  1) Set up a honeypot that detects MSF scans/attacks (somehow).
  2) Once I get a probe, fire back a logout request.
  3) Continue to logout the active user forever.
  
  It's less damaging than a traditional "hack back" but is sure to irritate the local red team to no end. It's essentially a user DoS. This attack may have been useful as a denial of service against Metasploit instances, allowing an attacker to prevent normal Metasploit usage.
