Summary

Ricoh printers and MFPs do not restrict SSH port forwarding. When SSH is enabled, attackers can use port forwarding to connect to arbitrary hosts on the LAN.

Risk Assessment

This allows attackers to access other devices on the internal network, potentially leading to further exploitation and data breaches.

Recommendation

Disable SSH on Ricoh devices if not needed, or apply firewall rules to block unauthorized port forwarding.
