Unitronics VisiLogic < 9.9.00 Default Password

critical Nessus Plugin ID 191550

Language:

Synopsis

The remote host is missing a security update.

Description

The version of Unitronics VisiLogic installed on the remote host is prior to 9.9.00. It is, therefore, affected by a vulnerability.

- 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. (CVE-2023-6448)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Unitronics VisiLogic to version 9.9.00 and follow the remediation advice from the vendor advisory.
