Impact
Authenticated network attackers can bypass authentication controls to read and modify sensitive data or compromise PLC operations. They need low-privilege network access to the device.
Root cause
Improper authentication logic in the UniLogic management software allows validation bypass.
Affected systems
Unitronics UniStream Pro (B10 / C10) running UniLogic versions prior to 1.41.329
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:L
Fix & remediation
Upgrade UniLogic to version 1.41.329 or later and re-flash the affected UniStream Pro PLC. If updating immediately is not possible, restrict network access to the PLC interface via firewall rules or isolate it on an out-of-band management VLAN.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
