Because these errors can occur but you should still be able to get a shell.

April 21, —KB (OS Build ) – Improvements and fixes

With root privileges Windows Subsystem for Linux WSL allows users to create a bind shell on any port no elevation needed. Don’t know the root password? 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.

The following example is calling a remote binary via an SMB share. If you have local administrator access on a machine try to list shadow copies, it’s an easy way for Privilege Escalation. If we found a privileged file write vulnerability in Windows or in some third-party software, we could copy our own version of windowscoredeviceinfo.

Check the vulnerability with the following nmap script or crackmapexec: crackmapexec smb Skip to content. Star Code Pull requests Projects Security Insights. Permalink master. Branches Tags.

HistorySavePath sls passw. NOTE: spaces are mandatory for this exploit to work! It looks like it is trying to import a module named mysmb , so in order for this to work, we need to download it. We can easily do that using wget. It looks like usage information now, which is a good sign.

We need to plug in the IP address of our target and a pipe name as parameters. Named pipes are a way for running processes to communicate with each other with very little overhead. Pipes usually appear as files for other processes to attach to. Metasploit has a scanner that will find any named pipes on a host. In a new terminal, type msfconsole to fire it up, then we can search for the scanner.

Load the module with the use command. Now we can take a look at the options. Now we should be able to run the exploit file.

Back in the first terminal from Step 1, where we’re still in the exploit directory, use the target’s IP address and one of the named pipes we found as parameters. We can see some data spit out on the screen, and at the bottom, it says it created a text file on the target. If we take a peek at the target, we can see this was successful. But we want to do more than just create a text file on the target. This is just a proof of concept, after all, so we will need to do a few more things to get this exploit fully functional.

We’re going to need a payload and a way for the exploit to get it and execute. For that, we can use MSFvenom to generate some shellcode, and we can serve it from our machine using Apache.

In a new terminal, use the following command to generate the payload and save it to a file named sc. Now we can start the Apache server so the exploit can connect to our machine from the target to reach the payload. Next, we will tweak the code to fit our needs.

Back in exploit. Here we can see the code that is responsible for connecting to the target and creating the text file. We can use this function to grab our payload and execute it on the target. Then we enter the name of the remote file being hosted on our machine and the name of the local file once it’s transferred. The code will look like this:. Finally, we can comment out the section that creates a text file, since we really don’t need it anymore. The final code should look like this:.

To complete the exploit, we need something to catch the shell once the payload executes. We can use the multipurpose handler in Metasploit for this. In a new terminal, use the following commands. We just need to set the payload to match whatever we specified when we created the shellcode earlier, which in this case is a reverse TCP shell. It will listen for any incoming connections, and if everything goes smoothly, we’ll get a Meterpreter session once our exploit completes.

At last, we should have everything in place and ready to go. We can launch the exploit just like we did earlier in our test run from within the exploit directory. This time we should see different results. Ignore the errors, and if it doesn’t work the first time, just try again. Once the exploit successfully completes, we should see a session open up back on our listener.

In this tutorial, we covered how to manually exploit EternalBlue on Windows Server. We began by setting up a few things in order to get the proof of concept to work.

Next, we generated some shellcode and hosted the payload on our machine. After that, we modified the code, launched the exploit, and successfully got a Meterpreter session on the target. Even though Metasploit contains a module to do all this automatically, it’s beneficial to know how to do things the hard way, just in case something needs tweaking for a specific target or scenario.
