Verify All Account Password Hashes are Shadowed
Medium Severity
If any password hashes are stored in
/etc/passwd
(in the second field, instead of an
x
or
*
), the cause of this misconfiguration should be investigated. The account should have its password reset and the hash should be properly stored, or the account should be deleted entirely.
