Senserva AI Opinion for KB5053602

KB5053602 is the March 11, 2025 rollup for Windows 10 version 1809 and Windows Server 2019, fixing 33 CVEs with a top rating of High (CVSS 8.8). At least one of these flaws is listed in the CISA Known Exploited Vulnerabilities catalog and is linked to ransomware activity, and the highest EPSS score here reaches 59 percent, meaning active exploitation is a present concern rather than theoretical. Server 2019 domain controllers and any remaining 1809 endpoints are directly exposed.

Do this: Deploy KB5053602 to all Windows Server 2019 and Windows 10 1809 systems now, prioritizing internet-facing hosts and domain controllers given the KEV and ransomware linkage.

Citrix

Applies to: All users

Symptoms

Devices that have certain Citrix components installed might be unable to complete installation of the January 2025 Windows security update. This issue was observed on devices with Citrix Session Recording Agent (SRA) version 2411. The 2411 version of this application was released in December 2024.

Affected devices might initially download and apply the January 2025 Windows security update correctly, such as via the Windows Update page in Settings. However, when restarting the device to complete the update installation, an error message with text similar to “Something didn’t go as planned. No need to worry – undoing changes” appears. The device will then revert to the Windows updates previously present on the device.

This issue likely affects a limited number of organizations as version 2411 of the SRA application is a new version. Home users are not expected to be affected by this issue.

Workaround

The issue has been resolved in Citrix Session Recording Agent version 2503, released on April 28, 2025, and newer versions.

For details, see the documentation provided by Citrix at " Microsoft's January Security Update Fails/Reverts on a machine with 2411 Session Recording Agent ".
