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

NOTE: The following commands must be run in the BASH shell. Check the ownership of local initialization files. Procedure: # ls -al //.login # ls -al //.cshrc # ls -al //.logout # ls -al //.profile # ls -al //.bash_profile # ls -al //.bashrc # ls -al //.bash_logout # ls -al //.env # ls -al //.dtprofile # ls -al //.dispatch # ls -al //.emacs # ls -al //.exrc # find //.dt ! -fstype nfs ! -user -exec ls -ld {} \; If local initialization files are not owned by the home directory's user, this is a finding.

Fix text

Change the ownership of the startup and login files in the user's directory to the user or root, as appropriate. Examine each user's home directory and verify all filenames beginning with "." are owned by the owner of the directory or root. If they are not, use the chown command to change the owner to the user and research the reasons why the owners were not assigned as required. Procedure: # chown username .filename 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.
