Title

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 '^#' # grep -i StrictModes /etc/openssh/sshd_config | grep -v '^#' If the setting is present and not set to yes, this is a finding.
