CVE-2022-29186Network attack vector

Unauthorized SSH access via pre-generated private key

Published May 20, 2022 · Updated Apr 23, 2025

Hard-coded SSH keys in PagerDuty Rundeck Docker images 4.0 and earlier allow remote attackers to access hosts configured with the exposed key. The Ubuntu base-image Dockerfile generated one SSH key pair at build time, so every resulting image exposed the same private credential. Exploitation requires an operator to copy the bundled public key into a remote host's authorized_keys file; access carries that account's privileges.
