Senserva AI Opinion for CVE-2024-38200

CVE-2024-38200 is a spoofing flaw in Microsoft Office 2019 and Microsoft 365 Apps for Enterprise that can leak a user's NTLM credentials to an attacker-controlled endpoint when a crafted file is opened. It is rated Medium severity (CVSS 6.5) with a 20 percent EPSS score and is not listed in CISA KEV, but the credential-exposure angle makes it more consequential than the score suggests for organizations still relying on NTLM. Anyone running the listed Office and Microsoft 365 Apps builds is exposed.

Do this: Deploy the current Microsoft Office and Microsoft 365 Apps security updates to the affected builds, and block outbound NTLM to external hosts at the network egress.
