Microsoft has released an out-of-band update for Windows Server 2022, designated as KB5070884 (OS Build 20348.4297). This update aims to enhance the operating system's stability and security by providing various quality improvements and critical security fixes. Among the significant issues addressed is a remote code execution vulnerability in the Windows Server Update Services (WSUS) reporting web services, identified as CVE-2025-59287.
In conjunction with this update, a servicing stack update, KB5066781 (OS Build 20348.4285), has also been introduced, which focuses on improving the reliability and robustness of the servicing stack—an essential component for the installation of Windows updates. Ensuring that the servicing stack is reliable is crucial for the seamless deployment of Microsoft updates.
While this update is designed to enhance system performance and security, users may experience some known issues post-installation. One such issue is the inability to view synchronization error details within WSUS's error reporting feature. This temporary drawback is a consequence of the measures taken to mitigate the remote code execution vulnerability.
For further details about servicing stack updates and their critical role in ensuring effective Windows update deployments, users are encouraged to refer to Microsoft's comprehensive guide on simplifying the on-premises deployment of these updates.
As information technology evolves, staying up-to-date with such critical updates is essential for maintaining system integrity and security. Organizations should prioritize the installation of updates like KB5070884 to protect against vulnerabilities and ensure smooth operational continuity. Regular monitoring of Microsoft's updates and advisories can help IT administrators safeguard their environments effectively
