10.0 CRITICAL

Remote, low-complexity, unauthenticated proxy abuse (AV:N/AC:L/PR:N/UI:N); segmentation bypass reaches other systems, giving scope change (S:C) with high C/I/A on exposed OT assets.

DescriptionCVE.org

Pronetiqs IntraVUE versions 3.2.1a14 and prior have an unintended proxy or intermediary vulnerability which could allow an attacker to use an active proxy, which would bypass OT segmentation.

AnalysisAI

Network-segmentation bypass in Pronetiqs (Panduit) IntraVUE 3.2.1a14 and earlier lets a remote, unauthenticated attacker abuse the product as an active proxy/intermediary to relay traffic across otherwise-isolated OT boundaries. Because IntraVUE typically sits with visibility into both IT and industrial control network segments, this confused-deputy behavior effectively neutralizes the network zoning that protects OT assets. …

Vulnerability AssessmentAI

Exploitation The exploit requires network reachability to an IntraVUE instance (version 3.2.1a14 or earlier) that is positioned with connectivity spanning the segmentation boundary the attacker wishes to cross - IntraVUE's normal deployment as a cross-segment network-discovery tool is itself the enabling condition. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment All available severity signals point the same direction: the CVSS 3.1 vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H yields a maximal 10.0, indicating remote, low-complexity, unauthenticated exploitation with a scope change into adjacent (OT) systems. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who can reach an exposed IntraVUE instance from an IT-side or otherwise untrusted network sends requests that coerce IntraVUE into proxying traffic through to devices in a segmented OT zone. Using this relay, the attacker reaches PLCs, HMIs, or other assets that firewall/VLAN segmentation was intended to isolate, then reads or manipulates OT communications. …
Remediation No vendor-released patch version is identified in the available data; consult CISA advisory ICSA-26-204-04 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-204-04) for the vendor's fixed build and upgrade guidance, and apply the vendor-remediated release as the primary fix once confirmed. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: identify all instances of IntraVUE 3.2.1a14 and earlier in your environment, confirm whether each has visibility into both IT and OT network boundaries, and implement immediate network-level isolation by restricting IntraVUE's outbound relay capability (e.g., firewall rules limiting its lateral connectivity). …
