A use of hard-coded cryptographic key vulnerability in FortiSIEM version 5.2.6 may allow a remote unauthenticated attacker to obtain SSH access to the supervisor as the restricted user "tunneluser" by leveraging knowledge of the private key from another installation or a firmware image.

Remedy

Please upgrade to FortiSIEM version 5.2.7 and above where this issue is resolved. Workaround (for FortiSIEM version 5.2.6 and lower): Customers who are not using the reverse tunnel feature are advised to disable SSH service on port 19999 by following the steps below : 1. SSH to the Supervisor node as the root user. 2. Remove tunneluser SSH configuration file to disable listening on port 19999: rm -f /etc/ssh/sshd_config.tunneluser echo rm -f /etc/ssh/sshd_config.tunneluser >> /etc/init.d/phProvision.sh 3. Then terminate sshd running on TCP Port 19999 as follows: pkill -f /usr/sbin/sshd -p 19999 4.Additional steps can be performed on Supervisor to remove the keys associated with tunneluser account: rm -f /opt/phoenix/deployment/id_rsa.pub.tunneluser rm -f /home/tunneluser/.ssh/authorized_keys rm -f /opt/phoenix/id_rsa.tunneluser ~admin/.ssh/id_rsa Customers are also advised to disable "tunneluser" SSH access on port 22 by following the steps bwlow: 1. SSH to the Supervisor node as the root user. 2. Add/edit the following line in sshd_config file: echo DenyUsers tunneluser >> /etc/ssh/sshd_config 3. service sshd restart
