Any user who could send data to port 135 - the port on which the endpoint mapper runs - could potentially exploit the vulnerability. If MSRPC (Microsoft Remote Procedure Call) on port 135 is open, it indicates a potential target for enumeration. This includes the MS-RPC Endpoint Mapper service MSRPC was originally derived from open source software but has been developed further and copyrighted by Microsoft. It also has several other options including definable * bindshell and Initiated by the client application, the MSRPC process involves calling a local stub procedure that then interacts with the client runtime library to prepare and transmit the request to the server.
