Authenticated code execution via improper memory locking
Published Apr 11, 2023 · Updated Jan 23, 2025
Remote code execution in Microsoft Windows DNS Server allows remote authenticated users to execute code through network requests. Microsoft maps the flaw to sensitive data stored in improperly locked memory but has not published the affected routine or how request data reaches it. Exploitation requires high privileges and high attack complexity; successful exploitation compromises confidentiality, integrity, and availability.
