A few quick notes on the Erlang OTP SSHd RCE (CVE-2025-32433):
1. Cisco confirmed that ConfD and NSO products are affected (ports 830, 2022, and 2024 versus 22)
2. Signatures looking for clear-text channel open and exec calls will miss exploits that deliver the same payloads after the key exchange.
3. If you find a machine in your environment and can't disable the service, running the exploit with the payload `ssh:stop().` will shut down the SSH service temporarily.
