Senserva AI Opinion for KB5002618
KB5002618 patches Microsoft SharePoint Enterprise Server 2016, SharePoint Server 2019, and SharePoint Server Subscription Edition, fixing four CVEs, CVE-2024-38023, CVE-2024-38024, CVE-2024-32987, and CVE-2024-38094. The top flaw is High severity at CVSS 7.5, but it is both in the CISA KEV catalog and tied to ransomware activity with a 53 percent EPSS score, so an on premises SharePoint farm left unpatched is a documented path into ransomware incidents. SharePoint's role as a shared document store makes a compromise here especially damaging for lateral movement.
Do this: Patch all on premises SharePoint Server farms with KB5002618 given the confirmed ransomware and CISA KEV linkage.
