Prior to version 6. In particular cases this may allow an attacker to bypass security features or execute arbitrary code. Furthermore in case an attacker has some control over the read flash memory, this may result in нажмите для деталей of arbitrary code and platform compromise. A fix for this issue has been included in USBX release 6.

Its goal is to make it easier to share data across separate vulnerability capabilities tools, databases, and services. But according to the researcher, the bug was not fixed correctly. He discovered a new variant during the analysis of the CVE patch.
The researcher published a new version of the proof of concept PoC exploit, which is even more powerful than the original exploit. A quick search on VirusTotal showed dozens of different files that tried to do this. This may be some threat actors testing the exploit code to turn it into something they can use in their attacks, along with some researchers trying out different ways to use and stop the exploit. It is worrying nonetheless to see once again how quick attackers are able to weaponize publicly available exploit code.
So you better wait and see how Microsoft will screw the patch again. In the meantime, Malwarebytes Premium and business users are protected, because our programs detect the files using this vulnerability as Exploit. In fact, only 5 vulnerabilities were patched in Other products include those by Microsoft 27 , Adobe 16 , and Oracle 7.
Since Adobe no longer supports Flash Player, on January 12, , the company started blocking Flash content from running. Last year, you would typically see exploited vulnerabilities that would allow an attacker to breach a network or compromise a system to gain a foothold.
This allows attackers to exfiltrate data, plant ransomware, and other criminal activities that could lead to financial gain. However, they would NOT gain privileges to view or modify file contents. Successful exploitation of these vulnerabilities could result in denial of service, information disclosure or remote code execution. Could it be that, no surprise, the war in Ukraine has changed the nature of the actively exploited vulnerabilities?
And those are just some of the attacks we know about. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Windows Installer service. By creating a junction, an attacker can abuse the service to delete a file or directory. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
CVE was among them. However, installing this patch does not completely eliminate the vulnerability. All the versions of Windows 10, Windows 11 and Windows server are affected by this vulnerability. Any attempt to directly patch the binary will result in a failure of the Windows installer. We must wait for Microsoft to resolve this issue.
The original CVE allows an attacker to delete files on a system using elevated privileges. Also, of note, is our research shows that attackers using this exploit can easily evade detection by AV. However, before the December update, a remote low-privileged user really could write arbitrary files on system-assigned unconstrained delegation. The issue seems to persist despite multiple patch attempts. But as I touched upon, it can be paired with a local vulnerability to achieve remote code execution, and as such, I thought it deserved more attention.
It allows an attacker to force a victim Windows computer to authenticate to a third party e. The full chain is interesting, but this discussion is only interested in the initial portion triggered by PetitPotam. The attack is quite simple. The third-party server can then tell the victim to authenticate in order to access the share, and the victim obliges. That means an attacker can also bypass the patch by switching named pipes. The following output shows PetitPotam forcing a Domain Controller patched through November to authenticate with an attacker controlled box running Responder.
If the client fails to do so, then the client is rejected and a Windows application event is generated. First, the file-writing aspect of this vulnerability only appears to work on systems with unconstrained delegation. This means a low-privileged attacker can only write to the places where they have permission e. 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. It looks like this exploit uses a list of named pipes to check and connects to a share. We can leave all this as default for now, but we need to set the remote host. Despite all the damage EternalBlue has caused, there is one reliable way to prevent these types of exploits: patch your systems!
At this point, nearly two years since these vulnerabilities were disclosed, there is really no excuse to have unpatched operating systems. EternalBlue continues to be a problem, though, and even though the consequences are dire, unfortunately, some organizations will still be running unpatched systems.
That, combined with pirated versions of Windows, makes EternalBlue a significant threat to this day. Cryptojacking, which uses a victim's computer to secretly mine cryptocurrency , is another threat vector that uses EternalBlue to leverage attacks. WannaMine was one of these outbreaks that hijacked computers around the world in Today, we learned about EternalBlue and how to exploit it using Metasploit. We also learned about an exploit similar to EB that is more reliable and works on more systems.
In the next tutorial, we will dig a little deeper and learn how to exploit EternalBlue manually, which is much more satisfying in the end.
