Executive Summary

This vulnerability is a missing origin validation issue in the WebSockets implementation of the GraphicalData web services used by several PcVue features including WebVue, WebScheduler, TouchVue, and SnapVue in versions 12.0.0 through 16.3.3.

Because the origin of WebSocket connections is not properly validated, a remote attacker could trick an authenticated user into visiting a malicious website that could exploit this flaw.

The vulnerability specifically affects two endpoints: GraphicalData/js/signalR/connect and GraphicalData/js/signalR/reconnect.

Impact Analysis

This vulnerability might allow a remote attacker to lure a successfully authenticated user to a malicious website, potentially leading to unauthorized actions or data exposure through the affected WebSocket endpoints.

Since the attacker can exploit the missing origin validation, it could result in cross-site WebSocket hijacking or other attacks that leverage the user's authenticated session.
