Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2022-37958 is a remote code execution vulnerability in the SPNEGO Extended Negotiation (NEGOEX) Security Mechanism. It received a CVSS 3.1 base score of 8.1 reflecting network attack vector, high complexity, no required privileges or user interaction, and high impact across confidentiality, integrity, and availability.
An unauthenticated remote attacker could exploit the flaw to achieve arbitrary code execution on a vulnerable system, though successful exploitation requires overcoming the noted high attack complexity. The weakness resides in the negotiation protocol handling and could be triggered during authentication exchanges.
Microsoft has published an update guide for CVE-2022-37958 that directs administrators to the corresponding security patches. The associated EPSS probability has remained stable near 0.12 with no material post-disclosure climb.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires timely installation of the vendor security patches that close the NEGOEX RCE flaw.
Boundary-protection rules can restrict the network attack vector used to reach the vulnerable SPNEGO/NEGOEX handler.
Continuous monitoring of authentication traffic and anomalous protocol exchanges can identify attempted exploitation of the negotiation flaw.
