Credential disclosure via improperly permissioned scripts

Improper privilege handling in scripts in B&R APROL before 4.4-00P5 allows local users with authenticated access to read credentials. The affected scripts apply insufficient permission checks when handling credentials, but B&R has not identified the scripts or published the faulty operations. Exploitation requires an authenticated local account and exposes credentials without reported modification or service interruption.
