Description Matěj Týč 2020-04-30 09:04:47 UTC
Description of problem:

Rules

- xccdf_org.ssgproject.content_rule_file_permissions_ungroupowned
- xccdf_org.ssgproject.content_rule_no_files_unowned_by_user

may not work correctly if the system uses remote user/group backend s.a. LDAP.

Version-Release number of selected component (if applicable):

scap-security-guide-0.1.40-12.el7.noarch

Steps to Reproduce:

1. Scan a system where a remote user has their home directory

Actual results:

Scan will fail because of files in that directory, although they are legitimate.

Expected results:

Scan passes

Comment 2 Matěj Týč 2020-04-30 09:08:34 UTC
The OVAL language that is the language behind checks in SCAP as of 4/2020 has no means how to query the system about remote groups that would work with appropriate LDAP configurations.
The only way how to address the issue right now is to document this limitation in the rule prose.
