Check: GEN001475

IRIX 6.5: GEN001475 (in versions v1 r1 through v1 r0.6)

Title

The /etc/group file must not contain any group password hashes. (Cat II impact)

Discussion

Group passwords are typically shared and should not be used. Additionally, if password hashes are readable by non-administrators, the passwords are subject to attack through lookup tables or cryptographic weaknesses in the hashes.

Check Content

Check the /etc/group file for password hashes. Procedure: # cat /etc/group If any password hashes are returned, this is a finding. If no password hashes are returned, there is no finding.

Fix Text

Edit /etc/group and change the password field to an exclamation point (!) to lock the group password.
