CVE-2026-42933
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPronetiqs 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidencePronetiqs IntraVUE versions 3.2.1a14 and prior contains an unintended proxy/intermediary vulnerability that allows attackers to leverage the application as an active proxy. This architectural flaw enables malicious traffic to be routed through the IntraVUE system, effectively bypassing OT network segmentation and allowing access to otherwise isolated operational technology networks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify IntraVUE versionLocate the installed IntraVUE version number through the product's about page, version info in the management interface, or check installed software metadata on the host systemAffected if Version is 3.2.1a14 or any version prior to it
-
Review proxy configurationExamine IntraVUE network or proxy settings through the administrative interface to identify any unintended proxy rules or forwarding configurationsAffected if Proxy or forwarding rules exist that were not explicitly configured by the administrator
-
Audit network connectionsReview network traffic logs and connection tables to identify unexpected inbound connections from external networks being forwarded to internal OT networksAffected if IntraVUE is forwarding connections between different network segments without explicit authorization
-
Inspect firewall rulesCheck host-based or network firewall rules to determine if IntraVUE has been configured to accept and route traffic across segmented networksAffected if Firewall permits cross-segment traffic through IntraVUE that violates segmentation policies
If the installed IntraVUE version is 3.2.1a14 or earlier and the system is forwarding traffic across network segments without explicit administrator intent, the environment is affected by this unintended proxy vulnerability.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataOrganizations should immediately update to a patched version of IntraVUE once available. In the interim, implement strict network segmentation, firewall rules restricting proxy usage, and monitoring for anomalous traffic patterns through the IntraVUE system to detect potential exploitation.
