Vulnerability discussion

Local initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon logon.

Check content

Check user home directories for local initialization files with extended ACLs. Procedure: # cat /etc/passwd | cut -f 6,6 -d ":" | xargs -n1 -IDIR ls -le DIR/.login DIR/.cshrc DIR/.logout DIR/.profile DIR/.bash_profile DIR/.bashrc DIR/.bash_logout DIR/.env DIR/.dtprofile DIR/.dispatch DIR/.emacs DIR/.exrc Procedure: #aclget / and check if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL from the local initialization file(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.
