Authenticated remote code execution via crafted RPC traffic
Published Jan 12, 2021 · Updated Oct 8, 2024
Remote code execution in Microsoft Windows RPC Runtime allows remote authenticated users to execute code through crafted RPC traffic. Microsoft has not published the affected RPC routine or the unsafe operation performed on attacker-controlled input. Exploitation requires low-privileged credentials and network access, and successful exploitation runs code in the vulnerable RPC service context.
