Microsoft CVE-2022-38023: Patch Verification Steps for Zero-Day Exploits

Microsoft's CVE-2022-38023 zero-day flaw lets attackers hijack Windows systems with no user action—if your devices haven't been patched, they're already at risk.

This isn't just another update reminder. We're talking about a critical remote code execution vulnerability that Microsoft rated 9.8 out of 10—the highest possible. Attackers only need your IP address to gain complete control, and the patch rollout has left some organizations dangerously exposed.

The good news? Verifying your protection takes just 5 minutes using built-in Windows tools. Below, I'll walk you through exactly how to check your systems, what to do if they're still vulnerable, and why this exploit has security experts on high alert.

Whether you're a home user or IT admin, skipping this check could mean the difference between a secure system and one that's already compromised. Let's get your defenses in place before the next attack wave hits.

How to verify Microsoft CVE-2022-38023 patch installation on Windows systems

CVE-2022-38023 is a critical zero-day vulnerability in Windows that allows remote code execution with minimal user interaction. Microsoft released patches for this flaw in November 2022, but many systems remain unpatched. To ensure your Windows 10/11 devices are protected, follow these verification steps using built-in tools.

Before diving into checks, confirm your Windows version. This vulnerability affects Windows 10 (20H2, 21H2) and Windows 11 (21H2, 22H2). If you’re unsure, press Win + R, type winver, and check the build number.

Patches for this CVE are included in the November 2022 cumulative updates.

The most reliable methods to verify patch status include:

1. Windows Update History (GUI method)
2. PowerShell commands (automated check)
3. Registry inspection (manual validation)

Each method confirms whether the KB5019232 or later update is installed, which includes the CVE-2022-38023 fix.

⚠️ Critical Note: If any device in your network lacks this patch, it remains exposed to attacks exploiting this flaw. Attackers can execute arbitrary code on vulnerable systems without authentication, leading to data breaches or ransomware deployment.

For enterprise environments, use Windows Server Update Services (WSUS) or Group Policy to enforce patch deployment. Navigate to Computer Configuration > Policies > Administrative Templates > Windows Components > Windows Update and enable Configure Automatic Updates to 4 (Auto download and schedule install).

If a device fails all checks, prioritize installing the latest cumulative update immediately. Microsoft’s Security Update Guide (msrc.microsoft.com/update-guide) lists affected versions and patch details. For offline systems, download the standalone update package from the catalog and install manually.

Regularly monitor patch status using PowerShell scripts or third-party tools like Nessus or Qualys. Automate scans to detect unpatched devices in large networks. Proactive monitoring reduces exposure to zero-day exploits like CVE-2022-38023.

Remember: CVE-2022-38023 exploits can lead to complete system compromise. Verify patches across all devices—servers, workstations, and IoT systems—to maintain a secure network perimeter. 🔒

Critical system checks: detecting unpatched devices in your network

To prevent exploitation of CVE-2022-38023, you must first identify unpatched devices across your network. This zero-day flaw in Windows 10/11 allows attackers to execute code remotely—often before administrators realize the exposure.

Start by scanning for missing updates using native tools like Windows Update logs or Windows Server Update Services (WSUS). For larger environments, third-party solutions like Nessus or Qualys provide deeper visibility into patch compliance.

Manual checks can be time-consuming, but they’re critical. For example, verify the KB5007253 patch (the official fix for CVE-2022-38023) by checking the Installed Updates list in Control Panel or via PowerShell.

However, this only confirms patches on individual machines—not your entire network. Automated tools bridge this gap by cross-referencing Group Policy Objects (GPO) with device inventories to flag inconsistencies.

Comparison of Detection Methods

For Windows Server Update Services (WSUS), navigate to Reports > Computer Report and filter for devices missing KB5007253. This method scales efficiently but requires initial setup. Alternatively, use PowerShell to query update status remotely.

Run the command: Get-HotFix -ComputerName [DeviceName] | Where-Object { $_.HotFixID -notlike "_KB5007253_" } This script checks each machine’s installed updates against the CVE-2022-38023 patch ID.

If your network lacks centralized management, deploy third-party scanners like Nessus or OpenVAS. These tools actively probe systems for missing patches, including CVE-2022-38023, and generate actionable reports. For example, Nessus’s Windows plugin pack includes a dedicated check for this vulnerability, flagging devices within minutes of scanning.

Once you’ve identified unpatched devices, prioritize remediation. Isolate vulnerable machines from critical networks while deploying the patch. Use Group Policy to enforce updates across all devices, ensuring consistency. For example, create a GPO targeting Windows 10/11 machines to auto-install KB5007253 via Software Installation policies.

Regular audits are non-negotiable. Schedule monthly scans using your chosen method to catch new vulnerabilities early. Combine automated tools with manual checks to close gaps—especially in hybrid environments where some devices may bypass centralized updates. Proactive detection turns CVE-2022-38023 from a ticking time bomb into a managed risk.
