Vulnerability discussion

If other users have access to modify user-specific SSH configuration files, they may be able to log on to the system as another user.

Check content

Verify the SUSE operating system SSH daemon performs strict mode checking of home directory configuration files. Check that the SSH daemon performs strict mode checking of home directory configuration files with the following command: # sudo grep -i strictmodes /etc/ssh/sshd_config StrictModes yes If "StrictModes" is set to "no", is missing, or the returned line is commented out, this is a finding.

Fix text

Configure the SUSE operating system SSH daemon performs strict mode checking of home directory configuration files. Uncomment the "StrictModes" keyword in "/etc/ssh/sshd_config" and set the value to "yes": StrictModes yes

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.
