Last modified Jun 17, 2026

CVE-2022-30271 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. The Motorola ACE1000 RTU through 2022-05-02 ships with a hardcoded SSH private key and initialization scripts (such as /etc/init.d/sshd_service) only generate a new key if no private-key file exists. Thus, this hardcoded key is likely to be used by default.. EPSS estimates a 0.83% chance of exploitation in the next 30 days.
