Vulnerability discussion

An easily guessable password provides an open door to any external or internal malicious intruder. Many computer compromises occur as the result of account name and password guessing. This is generally done by someone with an automated script using repeated logon attempts until the correct account and password pair is guessed. Utilities, such as cracklib, can be used to validate passwords are not dictionary words and meet other criteria during password changes.

Check content

Check /etc/default/passwd for dictionary check configuration. # grep DICTION /etc/default/passwd If the DICTIONLIST or DICTIONDBDIR settings are not present, or are set to non-existent files or directories, this is a finding.

Fix text

Edit /etc/default/passwd; add or set DICTIONLIST to the dictionary file and DICTIONDBDIR to a database directory such as /var/passwd. Generate the password dictionary by running the mkpwdict command.

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.
