Netenberg Fantastico De Luxe 2.8 uses database file names that contain the associated usernames, which allows local users to determine valid usernames and conduct brute force attacks by reading the file names from /var/lib/mysql, which is assigned world-readable permissions by cPanel 9.3.0 R5.

fantastico in Cpanel does not properly handle when it has insufficient permissions to perform certain file operations, which allows remote authenticated users to obtain the full pathname, which is leaked in a PHP error message.
