CyberRota Analysis
AI-GeneratedOpenCTI versions prior to 7.260701.0 are vulnerable due to improper validation in the synchronizerFetch GraphQL query, which allows authenticated users with INGESTION capabilities to access internal services and cloud metadata endpoints. This flaw can lead to internal network scanning and potential exposure of sensitive internal data. Organizations using OpenCTI should prioritize upgrading to version 7.260701.0 to mitigate these risks.

Original NVD Description
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 7.260701.0, the synchronizerFetch GraphQL query called fetchRemoteStreams after checking only that a remote stream URL used HTTP or HTTPS. The backend did not apply the ingestion deny list or reject private, loopback, and link-local destinations, allowing an authenticated account with the INGESTION capability to make OpenCTI request internal services and cloud metadata endpoints. Returned connection errors could distinguish open HTTP ports, open non-HTTP ports, and closed ports, enabling internal network scanning, while compatible endpoint responses could disclose internal data. This issue is fixed in version 7.260701.0.
