Overview of this book

The book starts with a hands-on Day 1 chapter, covering the basics of the Metasploit framework and preparing the readers for a self-completion exercise at the end of every chapter. The Day 2 chapter dives deep into the use of scanning and fingerprinting services with Metasploit while helping the readers to modify existing modules according to their needs. Following on from the previous chapter, Day 3 will focus on exploiting various types of service and client-side exploitation while Day 4 will focus on post-exploitation, and writing quick scripts that helps with gathering the required information from the exploited systems. The Day 5 chapter presents the reader with the techniques involved in scanning and exploiting various services, such as databases, mobile devices, and VOIP. The Day 6 chapter prepares the reader to speed up and integrate Metasploit with leading industry tools for penetration testing. Finally, Day 7 brings in sophisticated attack vectors and challenges based on the user’s preparation over the past six days and ends with a Metasploit challenge to solve.

Phase-II: gaining access to the target

After completing the scanning stage, we know we have a single IP address, that is,, running HFS 2.3 file server and IIS 8.5 web services.


You must identify all the services running on all the open ports. We are focusing only on the HTTP-based services simply for the sake of an example.

The IIS 8.5 server is not known to have any severe vulnerabilities which may lead to the compromise of the entire system. Therefore, let us try finding an exploit for the HFS server. Metasploit offers a search command to search within modules. Let's find a matching module:

We can see that issuing the search HFS command, Metasploit found two matching modules. We can simply skip the first one as it doesn't correspond to the HFS server. Let's use the second one, as shown in the preceding screenshot. Next, we only need to set a few of the following options for the exploit module along with the payload:

Let's set the values for RHOST to, RPORT to 8080, payload to windows/meterpreter/reverse_tcp, SRVHOST to the IP address of our system, and LHOST to the IP address of our system. Setting the values, we can just issue the exploit command to send the exploit to the target, as shown in the following screenshot:

Yes! A meterpreter session opened! We have successfully gained access to the target machine. The HFS is vulnerable to remote command execution attack due to a poor regex in the file ParserLib.pas, and the exploit module exploits the HFS scripting commands by using %00 to bypass the filtering.
