The ‘check_univention_joinstatus’ prometheus monitoring script (and other scripts) in UCS 5.0-5 revealed the LDAP plaintext password of the machine account in the process list allowing attackers with local ssh access to gain higher privileges and perform followup attacks. By default, the configuration of UCS does not allow local ssh access for regular users.
