Multiple ICS Vulnerabilities Disclosed in November 2025 CISA Advisories

CISA published four new advisories detailing critical vulnerabilities affecting a range of industrial control system (ICS) products from Advantech, Ubia, and ABB. The vulnerabilities include improper input neutralization, path traversal, use of hard-coded credentials, insufficiently protected credentials, and improper validation of input types. Exploitation of these flaws could allow attackers to achieve remote code execution, denial-of-service, unauthorized access to camera feeds, or full remote control of affected devices. The impacted products are Advantech DeviceOn/iEdge (v2.0.2 and prior), Ubia Ubox (v1.1.124), and multiple ABB FLXeon controller models (various versions up to 9.3.5).

CISA recommends immediate review of the technical details and implementation of mitigations provided in the advisories. Notably, the Ubia Ubox vulnerability remains uncoordinated with the vendor, increasing risk for users. Organizations using these ICS products should prioritize patching, restrict network exposure, and follow CISA's defensive measures to minimize exploitation risk. The advisories underscore the ongoing threat to critical infrastructure posed by vulnerabilities in widely deployed ICS equipment.
