30 Jun 2022 — Sensitive data could be exposed in world readable logs of cloud-init before version 22.3 when schema failures are reported. This leak could include hashed passwords. Mike Stroyan discovered that cloud-init could log password hashes when reporting schema failures. An attacker with access to these logs could potentially use this to gain user credentials. • https://github.com/canonical/cloud-init/commit/4d467b14363d800b2185b89790d57871f11ea88c • CWE-532: Insertion of Sensitive Information into Log File •

10 Aug 2021 — When instructing cloud-init to set a random password for a new user account, versions before 21.2 would write that password to the world-readable log file /var/log/cloud-init-output.log. This could allow a local user to log in as another user. A flaw was found in cloud-init. When a system is configured through cloud-init and the "Set Passwords" module is used with "chpasswd" directive and "RANDOM", the randomly generated password for the relative user is written in clear-text in a file readable by any exist... • https://github.com/canonical/cloud-init/commit/b794d426b9ab43ea9d6371477466070d86e10668 • CWE-532: Insertion of Sensitive Information into Log File •

01 Aug 2018 — The default cloud-init configuration, in cloud-init 0.6.2 and newer, included "ssh_deletekeys: 0", disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks.
