Authenticated code execution via DNS race condition
Published Jul 11, 2023 · Updated Jan 1, 2025
Remote code execution in Microsoft Windows DNS Server allows remote authenticated users to execute code over the network. Microsoft maps the defect to sensitive data stored in improperly locked memory, while NVD also classifies it as a race condition; no public source identifies the affected function or input. Exploitation requires high privileges and a high-complexity race, and successful code execution can fully compromise the DNS server.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
