**********************************************************************
Discovered By: Kevin Randall on 3/23/2019
**********************************************************************
A Directory Traversal issue was discovered in the Web GUI in Titan FTP Server 2019 Build 3505.
When an authenticated user attempts to preview an uploaded file (through PreviewHandler.ashx) by using a \..\..\ technique, arbitrary files can
be loaded in the server response outside the root directory.
***********************************************************************
Tools used:

Parrot OS

Windows 7 32 Bit

BurpSuite

Browser
*************************************************************************
Vulnerability has been fixed in the following build:
Build: Titan FTP Server 2019 Build 3515
**************************************************************************
Proof of Concept (PoC):

Step 1: Authenticate through Titan FTP Web GUI

Step 2: Upload file and attempt to view it

Step 3: Intercept requests with BurpSuite when attempting to view uploaded file

Step 4: Modify "path=" and "filename=" parameters in the following GET request:
Ex: View contents of README.txt file in Python27 directory:
Note: You can access other files in directories such as System32, Desktop etc.
Payload:
*****************************************************************************************
GET /PreviewHandler.ashx?path=\..\..\..\..\Python27\README.txt&filename=README.txt
*****************************************************************************************
Step 5: If path is set-up correctly and if file exists, you will receive a 200 OK back from the server.

Step 6: View the file through the file preview in the FTP server.
