The Ultimate Guide to 2019-cve-0708 Patch Download and Installation
How to Download and Install the 2019-cve-0708 Patch for Windows
If you are using Windows Remote Desktop Protocol (RDP) on your system, you may be vulnerable to a critical security flaw that could allow remote attackers to execute arbitrary code on your machine. This flaw, known as 2019-cve-0708 or BlueKeep, affects older versions of Windows that are no longer supported by Microsoft, as well as some newer versions that have not been patched yet. In this article, we will explain what 2019-cve-0708 is, why it is important, how to check if your system is vulnerable, how to download and install the patch, and how to protect your system from future RDP exploits.
What is 2019-cve-0708 and Why is it Important?
2019-cve-0708 is a security vulnerability that was discovered in Microsoft's Remote Desktop Protocol (RDP) implementation, which allows for the possibility of remote code execution. RDP is a feature that enables users to remotely access and control another computer over a network. However, if an attacker can exploit this vulnerability, they can send specially crafted requests to the target system and run malicious code on it without requiring any authentication or user interaction. This could result in data theft, ransomware infection, network compromise, or other serious consequences.

A Critical Remote Code Execution Vulnerability in RDP
The vulnerability exists in the way RDP handles connection requests. Specifically, there is a flaw in the Remote Desktop Services component that processes these requests and allocates memory for them. An attacker can exploit this flaw by sending malformed packets that trigger a memory corruption error and allow them to execute arbitrary code in the context of the RDP service. This code can then perform any action that the RDP service has access to, such as installing malware, creating new accounts, modifying system settings, or deleting files.
A Potential Wormable Threat Similar to WannaCry
One of the most dangerous aspects of this vulnerability is that it is "wormable", meaning it can be used to create self-propagating malware that can spread from one vulnerable system to another without any user intervention. This is similar to how the infamous WannaCry ransomware exploited another RDP vulnerability (CVE-2017-0144) in 2017 and infected millions of computers worldwide. If a worm-based malware were to leverage 2019-cve-0708, it could potentially cause widespread damage and disruption across the internet.
A High-Risk Issue for Unsupported Windows Versions
Another factor that makes this vulnerability particularly serious is that it affects older versions of Windows that are no longer receiving mainstream support from Microsoft. This means that these versions do not get regular security updates and are more likely to be exposed to exploits. The affected versions include Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008. Microsoft has made an exception for this vulnerability and released patches for these unsupported versions, but many users may not be aware of them or have difficulty installing them. Therefore, it is crucial for users of these versions to download and apply the patches as soon as possible.
How to Check if Your System is Vulnerable to 2019-cve-0708
Before you download and install the patch, you may want to check if your system is actually vulnerable to 2019-cve-0708. There are several ways to do this, depending on your preference and technical skills. Here are some of the methods you can use:
Use the Microsoft Security Guidance Advisory
The easiest way to check if your system is vulnerable is to use the official Microsoft Security Guidance Advisory that provides information and links for this issue. You can find the advisory on the Microsoft Security Response Center website or by searching for "2019-0708" on the Microsoft Support website. The advisory will tell you which versions of Windows are affected, which patches are available, and how to obtain them. You can also use the advisory to check if your system has already been patched by comparing the file versions listed in the advisory with the ones on your system.
Use a Third-Party Vulnerability Scanner
Another way to check if your system is vulnerable is to use a third-party vulnerability scanner that can detect 2019-cve-0708. There are several tools available online that can scan your system or network for this issue, such as Nmap, Qualys, Rapid7, or Tenable. These tools can also provide you with more details and recommendations on how to fix the vulnerability. However, you should be careful when using these tools and only download them from trusted sources, as some malicious actors may try to exploit this vulnerability by distributing fake or infected scanners.
Use a PowerShell Script
If you are comfortable with using PowerShell, you can also use a PowerShell script that can check if your system is vulnerable to 2019-cve-0708. One such script is the BlueKeep Scanner created by Robert Graham, a security researcher who was among the first to discover and analyze this vulnerability. The script can scan a single system or a range of IP addresses for 2019-cve-0708 and report the results in a simple format. You can download the script from GitHub or run it directly from a PowerShell console.
How to Download the 2019-cve-0708 Patch for Your Windows Version

Use the Microsoft Update Catalog
The Microsoft Update Catalog is a website that provides direct links to download updates for various Microsoft products, including Windows. You can use this website to search for and download the patch for 2019-cve-0708 by entering "KB4499175" (for Windows Server 2008), "KB4499180" (for Windows Vista), "KB4500331" (for Windows XP and Windows Server 2003), or "KB4500705" (for other supported versions) in the search box. You will then see a list of results with different file names and sizes, depending on your system architecture (32-bit or 64-bit). You should select and download the file that matches your system type.
Use the Windows Update Service
The Windows Update Service is a feature that allows your system to automatically check for and install updates from Microsoft. You can use this feature to download and install the patch for 2019-cve-0708 by following these steps:
Open the Start menu and click on Settings.
Click on Update & Security.
Click on Check for updates.
