Vulnerability discussion

As an immediate return of an error message, coupled with the capability to try again, may facilitate automatic and rapid-fire brute-force password attacks by a malicious user.

Check content

Check the SLEEPTIME parameter in the /etc/default/login file. # grep ^SLEEPTIME /etc/default/login If the output is not SLEEPTIME=4 or more, this is a finding.

Fix text

The root role is required. # pfedit the /etc/default/login Locate the line containing: SLEEPTIME Change the line to read: SLEEPTIME=4

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.
