CISA Notification
CISA KEV (Known Exploited Vulnerabilities)

For the benefit of the cybersecurity community and network defenders—and to help every organization better manage vulnerabilities and keep pace with threat activity—CISA maintains the authoritative source of vulnerabilities that have been exploited in the wild.

Description :

Unitronics Vision Series PLCs and HMIs ship with an insecure default password, which if left unchanged, can allow attackers to execute remote commands.

Required Action :

Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Notes :

Note that while it is possible to change the default password, implementors are encouraged to remove affected controllers from public networks and update the affected firmware: https://downloads.unitronicsplc.com/Sites/plc/Technical_Library/Unitronics-Cybersecurity-Advisory-2023-001-CVE-2023-6448.pdf
