CVE-2022-30271Network attack vector

SSH server impersonation via hardcoded host key

Published Jul 26, 2022 · Updated Aug 3, 2024

Hardcoded credentials in Motorola Solutions ACE1000 RTU firmware through 2022-05-02 allow remote attackers to impersonate devices. The /etc/init.d/sshd_service initialization script generates a new SSH host key only when no private-key file exists, leaving the shipped key active by default. Exploitation requires a client to trust the reused device key and enables interception or manipulation of SSH maintenance and SFTP sessions.
