Vulnerability discussion

Information systems are capable of providing a wide variety of functions and services. Some of the functions and services, provided by default, may not be necessary to support essential organizational operations (e.g., key missions, functions).It is detrimental for software products to provide, or install by default, functionality exceeding requirements or mission objectives. Examples include, but are not limited to, installing advertising software, demonstrations, or browser plugins not related to requirements or providing a wide array of functionality, not required for every mission, that cannot be disabled.DBMSs must adhere to the principles of least functionality by providing only essential capabilities.Demonstration and sample database objects and applications present publicly known attack points for malicious users. These demonstration and sample objects are meant to provide simple examples of coding specific functions and are not developed to prevent vulnerabilities from being introduced to the DBMS and host system.

Check content

Review vendor documentation and vendor websites for vendor-provided demonstration or sample databases, database applications, objects, and files. Review the DBMS to determine if any of the demonstration and sample databases, database applications, or files are installed in the database or are included with the DBMS application. If any are present in the database or are included with the DBMS application, this is a finding. Check for the existence of EDB Postgres sample databases: postgres and edb. Execute the following SQL as enterprisedb: SELECT datname FROM pg_database WHERE datistemplate = false; If any databases are listed here that are not used by the application, this is a finding.

Fix text

Remove any unused sample databases from the DBMS. To remove a database, execute the follow SQL: DROP DATABASE ;

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.
