The network device must not allow SSH Version 1 to be used for administrative access.
SSH Version 1 is a protocol that has never been defined in a standard. Since SSH-1 has inherent design flaws which make it vulnerable to attacks, e.g., man-in-the-middle attacks, it is now generally considered obsolete and should be avoided by explicitly disabling fallback to SSH-1.
Configure the network device to use SSH version 2.
Review the configuration and verify SSH Version 1 is not being used for administrative access. If the device is using an SSHv1 session, this is a finding.
