Authenticated code execution via undisclosed use-after-free
Published Apr 11, 2023 · Updated Jan 23, 2025
Use-after-free in Microsoft Windows DNS Server allows remote authenticated users with high privileges to execute code through DNS traffic. Microsoft has not disclosed the freed object, code path, or DNS input that triggers the stale-memory access. Exploitation requires high privileges and complex conditions; successful execution occurs in the DNS Server service context.
