Microsoft April 2022 patches include actively exploited CVE

elevated vulnerability

Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.

Microsoft released April 2022 patches; CVE-2022-24521 is confirmed exploited in the wild and requires immediate patching.

On 13 April 2022 (Japan time), Microsoft published security patches addressing multiple vulnerabilities in Microsoft products. The IPA (Information-technology Promotion Agency, Japan) advisory warns that exploitation of these flaws could result in application crashes, system compromise, and data theft. Most critically, CVE-2022-24521 is confirmed by Microsoft to be actively exploited in the wild, triggering an urgent mitigation recommendation. The IPA advises immediate application of available patches via Windows Update to prevent further compromise. Individual environment-specific questions should be directed to the product vendor rather than IPA.

What this brief leaves out

This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.

It sits in a corpus of 13,854 reports from 146 sources, 616 of them written in the last seven days, and it grows through the day.

A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
