Vulnerability discussion

Application management functionality includes functions necessary for administration and requires privileged user access. Allowing non-privileged users to access application management functionality capabilities increases the risk that non-privileged users may obtain elevated privileges.The separation of user functionality from information system management functionality is either physical or logical and is accomplished by using different computers, different central processing units, different instances of the operating system, different network addresses, different TCP/UDP ports, virtualization techniques, combinations of these methods, or other methods, as appropriate.An example of this type of separation is observed in web administrative interfaces that use separate authentication methods for users of any other information system resources. This may include isolating the administrative interface on a different security domain and with additional access controls.

Check content

Review the application documentation and interview the application administrator. Review the design documents and the interfaces used by the application. Verify that the application provides separate interfaces for user traffic and for management traffic. The separation may be virtual in nature (virtual host, virtual NIC, virtual network) or physically separate. If the application user interface and the application management interface are shared, this is a finding.

Fix text

Configure the application so user interface to the application and management interface to the application is separated.

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.
