CVE-2004-1653 SSH port forwarding exposes unprotected internal services
An improper access control vulnerability in the admin SSH console of multiple products may allow an authenticated user to access internal only system services via using SSH local port forwarding.
A successful attack needs an authenticated admin SSH user to set up a port bounce to product internal only services via SSH local port forwarding; potential consequences are information disclosure and/or privilege escalation.
