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

Check run control script modes. # cd /etc # find rc* -ls If any run control script has a mode more permissive than 0755, this is a finding.

Fix text

Ensure all system startup files have mode 0755 or less permissive. Examine the rc files, all files in the rc1.d (rc2.d, and so on) directories, and in the /etc/init.d directory to ensure they are not world-writable. If the files are world-writable, use the chmod command to correct the vulnerability and research why they are world-writable. Procedure: # chmod 755 startupfile Document all changes.

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.
