CVE-2025-30234

Server impersonation via shared SSH host keys

Published Mar 19, 2025 · Updated Mar 19, 2025

Hard-coded SSH host keys in SmartOS image 60f76fd2-143f-4f57-819b-1ae32684e81b allow adjacent attackers to impersonate LX zones. The Debian 12 LX zone image embeds pre-generated private host keys under /etc/ssh, so zones cloned from it present the same server identities. Exposure requires a zone created from that exact image without subsequent key regeneration and an attacker positioned to intercept its SSH traffic.
