We can easily retrieve all the FTP usernames and password under a domain in plain text, by following the below steps.

1. Enter the MySQL Prompt.

# mysql -u admin -p`cat /etc/psa/.psa.shadow`

2. use psa;

3. mysql> select US.* FROM sys_users US, hosting HS, domains DM

-> WHERE US.id = HS.sys_user_id AND HS.dom_id = DM.id AND DM.name =’domain.com’;

The below given is a sample output of that command.

+—–+———-+———-+———————————–+————+——-+
