FTP Banner Grabbingįrom the above image we can see that the version is 1.3.1 and the operating system is Debian.There are many things that we can do from here.First we can try to find if there is any public exploit for the ProFTPD 1.3.1 version.If there is then we can launch it against the FTP Service. In order to do a banner grabbing in the FTP service we will just try to connect through our console to the FTP server. ![]() Of course we can use the Nmap for the discovery of the remote operating system and the service fingerprinting but in this tutorial we will not take advantage of that.īanner Grabbing is a technique that someone can use in order to extract information from application banners.For example if the remote host is a web server,we can try to connect through telnet.The banner results will give us an indication about the operating system and the type of the web server (Apache or IIS). Now the next logical step that we have to do is to identify which version the FTP application is running by using a method which called FTP banner grabbing. We can do a simple scan with Nmap in order to find the open ports. The first thing that we need to do is of course to identify which systems are running the FTP service (for the needs of this tutorial I have put only one system). FTP is a service that is commonly used in Web Servers from Webmasters for accessing the files remotely.So it is almost impossible not to find this service in one of our clients systems during an engagement.įor that reason we will try to cover in this article a scenario of a possible attack against the FTP Server. ![]()
