Unitronics VisiLogic before version 9.9.00, used in Vision and Samba PLCs and HMIs, uses a default administrative password. An unauthenticated attacker with network access can take administrative control of a vulnerable system.
The product initializes or sets a resource with a default that is intended to be changed by the product’s installer, administrator, or maintainer, but the default is not secure.
