Many times you may find that a service is exploitable, but the Metasploit module is not built to exploit that service version or the specific OS version. This is not uncommon, just think back to writing the exploit earlier. Depending on what DLLs may have been referenced, the module may not be updated for a specific OS. Additionally, if newer version of an OS comes out and the program or service is still viable, you may need to expand the module.

Think back to Chapter 5, Exploiting Services with Python, and how we did research to find if a Kernel was vulnerable. Consider how doing similar research may result in references to potential buffer overflow vulnerabilities. You can either start from scratch, or you can reverse a Metasploit module into a standalone Python script and easily test for the expanded capabilities. You can then incorporate the changes into the Metasploit module, or even create your own.

We are going to reverse the Metasploit module for the Sami...
