Description
dirsys/modules/auth.php in JBC Explorer 7.20 RC1 and earlier does not require authentication, which allows remote attackers to (1) delete auth.inc.php via the suppr parameter, and (2) re-create the auth.inc.php file with contents that specify a new account name and password for JBC Explorer via the login and password parameters.
