Authenticated code execution through undisclosed RPC flaw
Published Jan 12, 2021 · Updated Oct 8, 2024
Remote code execution in Microsoft Windows RPC Runtime allows remote authenticated users to execute code through a network RPC request. Microsoft has not published the vulnerable function or the input-handling error within the RPC Runtime, leaving the code-level mechanism undisclosed. Exploitation requires valid low-privileged access to a reachable RPC service and executes code in that service's security context.
