Microsoft UFO WebSocket Redirect Vulnerability

Publication date: 2026-10-06

Last updated on: 2026-10-06

Assigner: GitHub, Inc.

Description
Microsoft UFO is an open-source framework for intelligent automation across devices and platforms. Prior to 3.0.9, authenticated device registration through /api/devices can supply a permitted attacker-controlled WebSocket endpoint while aip/transport/websocket.py applies pinned_addresses only to the initial destination. The pinned websockets.connect() client follows cross-origin redirects and opens a new TCP connection before Galaxy performs its post-handshake peer-IP validation, allowing WebSocket upgrade requests to internal hosts reachable from the server. The confirmed impact is the internal connection and handshake request, and does not establish arbitrary HTTP methods, response-body disclosure, a completed AIP session, or cloud metadata access. This issue is fixed in version 3.0.9.

CWE-918 The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.

Executive Summary

Microsoft UFO before 3.0.9 allows authenticated attackers to register a device with a malicious WebSocket endpoint. The framework's WebSocket client does not properly validate the endpoint's origin after redirects, enabling connections to internal hosts reachable from the server. This bypasses IP validation checks during the handshake process.

Detection Guidance

This vulnerability involves improper WebSocket endpoint handling in Microsoft UFO versions prior to 3.0.9. Detection requires checking installed versions and monitoring network traffic for unexpected WebSocket connections to internal hosts. Inspect logs for /api/devices registration attempts with attacker-controlled endpoints. No specific commands are provided in the context.

Impact Analysis

An attacker could exploit this to initiate internal network connections from the server, potentially accessing internal services or hosts. However, it does not allow arbitrary HTTP methods, data disclosure, or full session establishment.

Mitigation Strategies

Upgrade Microsoft UFO to version 3.0.9 or later to address the vulnerability. Ensure all authenticated device registrations are reviewed for suspicious WebSocket endpoints. Monitor network traffic for unexpected internal connections originating from the server.
