Executive Summary

This vulnerability is a Cross-Site Scripting (XSS) issue affecting the OAuth web services used by the WebVue, WebScheduler, TouchVue, and SnapVue features of PcVue versions 12.0.0 through 16.3.3.

It allows a remote attacker to trick a legitimate user into loading content from another site when the user fails to authenticate successfully on an unknown application (with an unknown client_id).

The vulnerability specifically affects only the error page of the OAuth server.

Impact Analysis

This vulnerability can impact you by allowing an attacker to execute malicious scripts in the context of the affected OAuth error page.

Such an attack could trick users into interacting with malicious content, potentially leading to phishing, session hijacking, or other malicious activities.

However, the vulnerability requires user interaction (UI:P) and occurs only on the OAuth error page, which may limit the scope of exploitation.
