T 5.41 Misuse of a Unix system with the help of uucp

The UUCP (Unix-to-Unix copy) software package allows an exchange of ASCII and binary files between IT systems and the execution of commands on remote IT systems. UUCP was originally implemented on Unix systems but is now available for many other operating systems. During communication via UUCP, IT users at remote computers get privileges for the local computer. If these rights are not granted carefully, or restricted to a bare minimum, the local system is in danger of being misused. Masquerading via UUCP, e.g. by feigning a host using the relevant password, is also conceivable.
