Vulnerability discussion

When temporary and emergency accounts are created, there is a risk the temporary account may remain in place and active after the need for the account no longer exists.To address this, in the event temporary accounts are required, accounts designated as temporary in nature must be automatically terminated after an organization-defined time period. Such a process and capability greatly reduces the risk of accounts being misused, hijacked, or data compromised.

Check content

If a temporary user has been created on the workstation, you can check the expiration settings using the following command: sudo pwpolicy -u get-effective-policy | tr " " "\n" | grep "usingHardExpirationDate\|hardExpireDateGMT" The value of "usingHardExpirationDate" should be "1", and the value for the "hardExpireDateGMT" should be a valid date. If they are not set correctly, this is a finding.

Fix text

To set an expiration date for a temporary account, use the following command: sudo pwpolicy -u -setpolicy "usingHardExpirationDate=1 hardExpireDateGMT=mm/dd/yy"
