Information disclosure via observable response differences
Published May 22, 2025 · Updated May 22, 2025
Observable response discrepancy in Tridium Niagara Framework and Enterprise Security lets remote attackers infer data over a network. Tridium has not disclosed the affected component, request type, or response variation that exposes the inference oracle. No authentication or user interaction is required; the reported consequence is limited to indirect disclosure, with no integrity or availability effect.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <4.10.11
- Affected versionversion=0 <4.14.2
- Affected versionversion=0 <4.15.1
