Description The issue is related to an incorrect permission assignment for a critical resource in Juniper Networks Junos OS and Junos OS Evolved. This allows a local authenticated attacker to read configuration changes without having the necessary permissions. When a user with the respective permissions commits a configuration change, a specific file is created that is readable even by users with no permissions to access the configuration. This can lead to privilege escalation as the user can read the password hash when a password change is being committed.
