What it is

sshportal through 1.19.5 contains a missing authorization vulnerability in the management shell 'key show' command that allows authenticated non-admin users to obtain decrypted backend private SSH keys. Attackers can request predictable key names like 'default' or 'host' to retrieve private keys and connect directly to backend hosts, bypassing ACLs and session recording.
