Description
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 existing user of the system. The highest threat from this vulnerability is to data confidentiality and it may allow a local attacker to log in as another user.
