Check: GEN005500
VMware ESX 3 Server:
GEN005500
(in version v1 r2)
Title
The SSH daemon must be configured to only use the SSHv2 protocol. (Cat I impact)
Discussion
SSHv1 is not a DoD-approved protocol and has many well-known vulnerability exploits. Exploits of the SSH daemon could provide immediate root access to the system.
Check Content
Examine the sshd configuration file. cat /opt/ssh/etc/sshd_config | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v '^#' | grep -i "Protocol" If Protocol 2,1 or Protocol 1 are defined on a line without a leading comment, this is a finding.
Fix Text
Edit the configuration file and modify the Protocol line. Protocol 2 Restart sshd: /sbin/init.d/secsh stop /sbin/init.d/secsh start
