Authenticated remote code execution
Published Apr 13, 2021 · Updated Nov 19, 2024
Remote code execution in Microsoft Windows RPC Runtime allows remote authenticated users to execute code through network RPC traffic. Microsoft has not disclosed the affected function, RPC endpoint, malformed input, or unsafe operation in the runtime. Low privileges are required; successful exploitation executes attacker-controlled code on an affected Windows host, while the reachable service and execution context remain undisclosed.
