Vulnerability Number

V-271628

Group Title

SRG-OS-000073-GPOS-00041

Rule Version

OL09-00-001080

Severity

CAT II

CCI(s)

• CCI-004062 - For password-based authentication, store passwords using an approved salted key derivation function, preferably using a keyed hash.
• CCI-000803 - Implement mechanisms for authentication to a cryptographic module that meet the requirements of applicable laws, Executive Orders, directives, policies, regulations, standards, and guidance for such authentication.

Fix Recommendation

Lock all interactive user accounts not using SHA-512 hashing until the passwords can be regenerated with SHA-512.

To lock an account:

$ sudo passwd -l [username]

Check Contents

Verify that OL 9 interactive user account passwords are using a strong password hash with the following command:

$ sudo cut -d: -f1,2 /etc/shadow
nsauser:$6$kcOnRq/5$NUEYPuyL.wghQwWssXRcLRFiiru7f5JPV6GaJhNC2aK5F3PZpE/BCCtwrxRc/AInKMNX3CdMw11m9STiql12f/

Password hashes "!" or "*" indicate inactive accounts not available for logon and are not evaluated.

If any interactive user password hash does not begin with "$6", this is a finding.
