For an rcp\noperation, the server chooses which files/directories are sent to the\nclient. However, the rcp client only performs cursory validation of the\nobject name returned. A malicious rsh server (or Man-in-The-Middle\nattacker) can overwrite arbitrary files in a directory on the rcp client\nmachine. This is similar to CVE-2019-6111.
