The vulnerability is caused due to an error in in.telnetd when invoking the "login" program. This can be exploited to bypass authentication by providing a valid account as login name preceded by the "-f" option specifier. The vulnerability is reported in Solaris (SunOS 5.10 and 5.11). Other versions may also be affected. SOLUTION: Disable the telnet service or use it only in a trusted network environment.
