PHTN-67-000088
(in versions v1 r6 through v1 r1)
Title
The Photon operating system must configure sshd to use privilege separation. (Cat II impact)
Discussion
Privilege separation in sshd causes the process to drop root privileges when not needed, which would decrease the impact of software vulnerabilities in the unprivileged section.
Check Content
At the command line, execute the following command: # sshd -T|&grep -i UsePrivilegeSeparation Expected result: UsePrivilegeSeparation yes If the output does not match the expected result, this is a finding.
Fix Text
Open /etc/ssh/sshd_config with a text editor. Ensure that the "UsePrivilegeSeparation" line is uncommented and set to the following: UsePrivilegeSeparation yes At the command line, execute the following command: # service sshd reload
