The at.allow file must not have an extended ACL.

From AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE

Part of GEN003245

Associated with IA controls: ECLP-1

Associated with: CCI-000225

SV-38786r1_rule The at.allow file must not have an extended ACL.

Vulnerability discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. Unauthorized modification of the at.allow file could result in Denial of Service to authorized at users and the granting of the ability to run at jobs to unauthorized users.

Check content

#aclget /var/adm/cron/at.allow Verify if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the at.allow file and disable extended permissions. #acledit /var/adm/cron/at.allow

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
