Vulnerability discussion

Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation. If temporary accounts remain active when no longer needed, they may be used to gain unauthorized access. The risk is greater for the network device since these accounts have elevated privileges. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation.

Check content

Review the network device configuration to determine if it automatically disables or removes temporary accounts after 72 hours or is configured to use an authentication server that would perform this function. If the use of temporary accounts is prohibited, this is not a finding. If the network device or its associated authentication server does not automatically disable or remove temporary accounts after 72 hours, this is a finding.

Fix text

Configure the network device or its associated authentication server to automatically disable or remove temporary accounts after 72 hours. An acceptable method would be to place an expiration date on the account upon creation.

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.
