OT segmentation bypass via active proxy
Published Jul 23, 2026 · Updated Jul 23, 2026
Unintended proxy behavior in PRONETIQS IntraVUE 3.2.1a14 and earlier allows remote attackers to bypass OT segmentation. The public advisory does not identify the request handler, endpoint, or validation failure that lets an attacker use IntraVUE as an active intermediary. No authentication or user interaction is required; successful use makes traffic originate from the trusted IntraVUE side and exposes otherwise segmented OT assets.
