Microsoft Windows 7 : List of security vulnerabilities
We see a few things happen here, like the SMB connection being established and the exploit packet being sent. At last, we see a "WIN" and a Meterpreter session is opened. Sometimes, this exploit will not complete successfully the first time, so if it doesn't just try again and it should go through. We can verify we have compromised the target by running commands such as sysinfo to obtain operating system information. This exploit doesn't work very well on newer systems, and in some cases, it can crash the target machine.
Next, we will explore a similar exploit that is a little more reliable, but just as deadly. As if EternalBlue wasn't devastating enough, three more similar exploits were developed after it. These were combined into a single Metasploit module that also uses the classic psexec payload. It's considered more reliable than EternalBlue, less likely to crash the target, and works on all recent unpatched versions of Windows, up to Server and Windows The only caveat is this exploit requires a named pipe.
Named pipes provide a method for running processes to communicate with one another, usually appearing as a file for other processes to attach to. The Metasploit module automatically checks for named pipes, making it pretty straightforward to use as long as a named pipe is present on the target.
We can use Nmap as an alternative to the Metasploit scanner to discover if a target is vulnerable to EternalBlue. The Nmap Scripting Engine is a powerful feature of the core tool that allows all kinds of scripts to run against a target.
Here, we'll be using the smb-vuln-ms script to check for the vulnerability. Our target will be an unpatched copy of Windows Server Datacenter edition. Evaluation copies can be downloaded from Microsoft so you can follow along if you want. We can specify a single script to run with the --script option, along with the -v flag for verbosity and our target's IP address. First, change directories in case you're still running Metasploit.
Nmap will start running and shouldn't take too long since we are only running one script. At the bottom of the output, we'll find the results. We can see it lists the target as vulnerable, along with additional information like risk factors and links to the CVE.
Now that we know the target is vulnerable, we can go back to Metasploit and search for an appropriate exploit. The monthly rollup update is available via Windows Update only.
