PostgreSQL Default Unpassworded Account

high Nessus Plugin ID 10483


The remote database server can be accessed without a password.


It is possible to connect to the remote PostgreSQL database server using an unpassworded account. This may allow an attacker to launch further attacks against the database.


Log into this host and set a password for any affected accounts using the 'ALTER USER' command.

In addition, configure the service by editing the file 'pg_hba.conf' to require a password (or Kerberos) authentication for all remote hosts that have legitimate access to this service and to require a password locally using the line 'local all password'.
