Vulnerability discussion

User authentication can be used as part of the policy filtering rule sets. Some URLs or network resources can be restricted to authenticated users only. Users are prompted by the application or browser for credentials. Authentication service may be provided by the ALG as an intermediary for the application; however, the authentication credential must be stored in the site's directory services server.The CA API Gateway must be configured to direct authentication traffic to specific authentication servers/URLs.

Check content

Open the CA API Gateway - Policy Manager. Select the "Identity Providers" tab, right-click a Registered Identity Provider, such as an LDAP Identity Provider, and select "Properties". Verify that a list of "LDAP Host URLs" is provided for use in authentication against this provider. If all of the servers needed for authentication are not listed in accordance with organizational requirements, this is a finding.

Fix text

Open the CA API Gateway - Policy Manager. Select the "Identity Providers" tab, right-click a Registered Identity Provider such as an LDAP Identity Provider, and select "Properties". Add the additional "LDAP Host URLs" to the list in accordance with organizational requirements and click "Finish".

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.
