Vulnerability discussion

If the startup files are writable by other users, they could modify the startup files to insert malicious commands into the startup files.

Check content

Verify run control scripts have no extended ACLs. Check if extended permissions are disabled. # ls -l /etc/rc* # aclget /etc/rc* # aclget /etc/init.d If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the run control script(s) and disable extended permissions. #acledit /

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.
