Vulnerability discussion

A shared/group account credential is a shared form of authentication that allows multiple individuals to access the network device using a single account. If shared/group account credentials are not terminated when individuals leave the group, the user that left the group can still gain access even though they are no longer authorized. There may also be instances when specific user actions need to be performed on the network device without unique administrator identification or authentication. Examples of credentials include passwords and group membership certificates.

Check content

Review the documentation to verify that a procedure exists to change the account of last resort and root account password when users with knowledge of the password leave the group. If a procedure does not exist to change the account of last resort and root account password when users with knowledge of the password leave the group, this is a finding.

Fix text

Establish and document a procedure that requires the changing of the account of last resort and root account password when users with knowledge of the password leave the group. To change the password: 1. Log on to CounterACT's Administrator UI. 2. From the menu, select Tools >> Options >> User Console and Options >> Password and Login. 3. Enter a new password. Note: Use of a cryptographically generated password is recommended. Password must be stored in a locked safe and used only when necessary since individual accounts are required to be used to ensure non-repudiation.

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.
