Vulnerability discussion

If the DBMS were to allow any user to make changes to database structure or logic, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process.Accordingly, only qualified and authorized individuals must be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications.Unmanaged changes that occur to the database software libraries or configuration can lead to unauthorized or compromised installations.

Check content

Use psql to connect to the db as enterprisedb and run this command: \dp *.* If any unauthorized roles have unauthorized accesses, this is a finding. Definitions of the access privileges are defined here: http://www.postgresql.org/docs/current/static/sql-grant.html

Fix text

Revoke unauthorized privileges. The syntax is: REVOKE ON
