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

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 product as follow (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 SySS GmbH found a reflected cross-site scripting vulnerability in
the web application component of OpenText Secure MFT solution which can
be exploited from an attacker's perspectives.

The input field for searching stored files is not correctly sanitized and
therefore can be abused to inject arbitrary JavaScript statements.

This reflected cross-site scripting vulnerability can be exploited by an
authenticated attacker by manipulating a token and sending a specially 
crafted JavaScript code (see PoC section).

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

Proof of Concept (PoC):

The following URL using the JavaScript code 
    
    "><script>alert(1)</<script> 

as the value for the URL parameter "querytext" demonstrate the reflected
cross-site scripting vulnerability by showing a JavaScript alert box.

    https://[Secure MFT HOST]/userdashboard.jsp?querytext="><script>alert(1)</script>&button=Search&panel=search

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

Solution:

Update Secure MFT to one of the following versions or newer:

    * Secure MFT 2013 R3 P6
    * Secure MFT 2014 R2 P2
    * Secure MFT 2015 R1
    * Secure MFT 2015 R1 FP1
