SV-27126r1_rule The system must require passwords to contain no more than three consecutive repeating characters.

Vulnerability discussion

To enforce the use of complex passwords, the number of consecutive repeating characters is limited. Passwords with excessive repeated characters may be more vulnerable to password-guessing attacks.

Check content

Check the MAXREPEATS setting. # grep MAXREPEATS /etc/default/passwd If the MAXREPEATS setting is greater than 3, this is a finding.

Fix text

Edit /etc/default/passwd and set MAXREPEATS to 3.

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.
