January Patch Tuesday updates fix intranet server vulnerability

However, sometimes a vulnerability that is very critical is detected, and all cumulative updates address that particular issue, and that is precisely the case with this month’s updates

A severe vulnerability issue with intranet servers was fixed

According to the official Microsoft changelog, e very serious security vulnerability was fixed that targeted HTTPS-based intranet servers:

Addresses a security vulnerability issue with HTTPS-based intranet servers. After installing this update, HTTPS-based intranet servers cannot, by default, use a user proxy to detect updates.

Scans using these servers will fail if you have not configured a system proxy on the clients. If you must use a user proxy, you must configure the behavior using the policy Allow user proxy to be used as a fallback if detection using system proxy fails.

To ensure the highest levels of security, also use Windows Server Update Services (WSUS) Transport Layer Security (TLS) certificate pinning on all devices.

This change does not affect customers who are using HTTP WSUS servers. For more information, see Changes to scans, improved security for Windows devices.

Additionally, these update also address a security bypass vulnerability that affected the Printer Remote Procedure Call (RPC) binding handles authentication for the remote Winspool interface.

All things considered, it is solely up to you whether to update your Windows 10 PC or not, as you can easily pause your Windows Update menu from automatically downloading them for you.

However, due to the fact that this update does bring a lot of security fixes, including 91 CVEs, our advice is that you update as soon as possible.

If you have no idea how to prepare your PC for Patch Tuesday updates, then here is a list of best practices for Patch Tuesday that you should follow every month before applying these updates.
