The vulnerability description mentions that we can execute system commands using the os.execute() function. You will also notice that executing system commands is not one of the options. When you type the help command on the console you will be presented with a list of commands that you can use to control the Wing FTP server.
#WING FTP SERVER AUTHENTICATED COMMAND EXECUTION PASSWORD#
Not because of MD5s cryptographic weaknesses but because it can be brute forced very fast and lots of password hashes can be found in online databases. Using MD5 hashes (salted or unsalted) for passwords nowadays is a potential security issue. Lets MD 5 hash this password with Python using the following command. The admins.xml file can be found in the following location.
#WING FTP SERVER AUTHENTICATED COMMAND EXECUTION HOW TO#
Wing Ftp Server How To Exploit Thisįinally we will demonstrate how to exploit this vulnerability using Metasploit.Īfter installing the demo version on a local system we found out that a file named admins.xml contains the hashed administrator password. Then well have a look at how we can manually execute system commands using the lua interpreter in the administrator panel. Lets have a look first at how Wing FTP version 4.3.8 stores administrator credentials. One of them is through SQL injection when credentials are stored in a database.Īnother option is through local file inclusion when they are stored in files on the server. There are many ways to get a hold of credentials for web applications, depending on how they are installed and accessed.
#WING FTP SERVER AUTHENTICATED COMMAND EXECUTION WINDOWS#
In the case of Wing FTP 4.3.8 on Windows the arbitrary commands are executed with system privileges as we will demonstrate in this tutorial. When exploiting this vulnerability the executed commands will be in the context of the user running the vulnerable software.
#WING FTP SERVER AUTHENTICATED COMMAND EXECUTION SOFTWARE#
This part of the software can only be accessed by an authenticated administrator user. Some nice features I personally like about Wing FTP are the remote web based administration panel, the web based client, the virtual servers and of course the APIs. Wing FTP Server is actively maintained with regular monthly updates, the latest release is version 4.8.5 which was released in February 2017. Unauthenticated command execution vulnerabilities are way more dangerous as they reside in publicly accessible places and can be exploited by anyone without authentication.īefore we are going to analyse and exploit this vulnerability we will first have a look at Wing FTP Server in general and its extensive list of features. In this situation the vulnerability is still protected by an authentication layer because the vulnerability resides in the administrator panel. Type the show options command to see what required fields we need to populate.Īuthenticated command execution vulnerabilities allow an authenticated attacker to execute arbitrary commands on the target system. In addition, the user is provided with the ability to copy the chart image to the clipboard allowing one to easily integrate DiskPulse charts into presentations and documents.ĭiskPulse Enterprise allows one to define a centralized set of report analysis rules, which are automatically applied to disk change monitoring reports received from production servers, detect critical file system changes and send E-Mail notifications. And if you are not sure which version is right for you, please see the edition difference here.
