To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server.
The security update addresses the vulnerabilities by correcting how SMBv1 handles these specially crafted requests. The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:. Microsoft has not identified any mitigating factors for these vulnerabilities.
The following workarounds may be helpful in your situation:. See Microsoft Knowledge Base Article Alternative method for customers running Windows 8. How to undo the workaround.
Retrace the workaround steps, and select the SMB1. An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 1. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server.
The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests. Microsoft has not identified any mitigating factors for this vulnerability. Microsoft recognizes the efforts of those in the security community who help us protect customers through coordinated vulnerability disclosure.

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.
