Vulnerability discussion

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

Check content

Check the SSH daemon configuration for the StrictModes setting. # grep -i StrictModes /etc/ssh/sshd_config | grep -v '^#' If the setting is present and set to "no", this is a finding. If the setting is not present or is set to "yes", this is not a finding.

Fix text

Edit the /etc/sshd/sshd_config file and remove the StrictModes setting or change the value of the StrictModes setting to "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.
