Check: GEN006210

SUSE Linux Enterprise Server v11 for System z STIG: GEN006210 (in versions v1 r12 through v1 r9)

Title

The /etc/smbpasswd file must not have an extended ACL. (Cat II impact)

Discussion

If the permissions of the "smbpasswd" file are too permissive, it may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.

Check Content

Check the permissions of the Samba password files. Procedure: # ls -lL /etc/samba/passdb.tdb /etc/samba/secrets.tdb If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all /etc/samba/passdb.tdb /etc/samba/secrets.tdb
