Vulnerability discussion

Within the database, object ownership implies full privileges to the owned object, including the privilege to assign access to the owned objects to other subjects. Database functions and procedures can be coded using definer's rights. This allows anyone who utilizes the object to perform the actions if they were the owner. If not properly managed, this can lead to privileged actions being taken by unauthorized individuals.Conversely, if critical tables or other objects rely on unauthorized owner accounts, these objects may be lost when an account is removed.

Check content

At the command prompt, execute the following command: # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "\dp;" Review the Access Privileges column. If any tables have permissions to users other than "postgres", this is a finding.

Fix text

At the command prompt, execute the following command: # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "ALTER TABLE OWNER TO postgres;" Replace with the name of the table discovered during the check.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
