Vulnerability discussion

An isolation boundary provides access control and protects the integrity of the hardware, software, and firmware that perform security functions. Security functions are the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based.Developers and implementers can increase the assurance in security functions by employing well-defined security policy models; structured, disciplined, and rigorous hardware and software development techniques; and sound system/security engineering principles. Database Management Systems typically separate security functionality from non-security functionality via separate databases or schemas. Database objects or code implementing security functionality should not be commingled with objects or code implementing application logic. When security and non-security functionality are commingled, users who have access to non-security functionality may be able to access security functionality.

Check content

At the command prompt, execute the following command: # /opt/vmware/vpostgres/current/bin/psql -U postgres -c "\dp .*.;" Review the Access Privilege column for all Schemas listed as "information_schema" and "pg_catalog". If access privilege is granted to any 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 "REVOKE ALL PRIVILEGES ON FROM ;" Replace and with the Access Privilege name and account, respectively, 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.
