You can replace the binary, restart the service and get system. Note to check file permissions you can use cacls and icacls. Using accesschk from Sysinternals or accesschk-XP. With root privileges Windows Subsystem for Linux WSL allows users to create a bind shell on any port no elevation needed.

Now start your bind shell or reverse. Binary bash. All Windows services have a Path to its executable. If that path is unquoted and contains whitespace or other separators, then the service will attempt to access a resource in the parent path first. Use the cmdkey to list the stored credentials on the machine.

The following example is calling a remote binary via an SMB share. EternalBlue is an exploit most likely developed by the NSA as a former zero-day.

It was released in by the Shadow Brokers , a hacker group known for leaking tools and exploits used by the Equation Group , which has possible ties to the Tailored Access Operations unit of the NSA. SMB allows systems to share access to files, printers, and other resources on the network. The vulnerability is allowed to occur because earlier versions of SMB contain a flaw that lets an attacker establish a null session connection via anonymous login.

An attacker can then send malformed packets and ultimately execute arbitrary commands on the target. We’ll be using an unpatched copy of Windows Server R2 as the target for the first section of this tutorial. An evaluation copy can be downloaded from Microsoft so that you can better follow along. The first thing we need to do is open up the terminal and start Metasploit.

Type service postgresql start to initialize the PostgreSQL database, if it is not running already, followed by msfconsole. Next, use the search command within Metasploit to locate a suitable module to use. There is an auxiliary scanner that we can run to determine if a target is vulnerable to MS It’s always a good idea to perform the necessary recon like this. Otherwise, you could end up wasting a lot of time if the target isn’t even vulnerable. Once we have determined that our target is indeed vulnerable to EternalBlue, we can use the following exploit module from the search we just did.

That should be everything, so the only thing left to do is launch the exploit. Use the run command to fire it off. 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.

In this guide, we’ll tackle the manual route of exploiting EternalBlue on Windows Server. I’ll be using an unpatched copy of Windows Server Microsoft Windows 7// R2/ R2/ R2 – ‘EternalBlue’ SMB Remote Code CVE remote exploit for Windows platform.

This program cannot be run in DOS mode. Ensures we log into the right domain. So this exploit should never crash a target against Windows 7 and later.
