Executive Summary

This vulnerability involves insufficient protection of credentials in Sparx Systems Pty Ltd's Sparx Enterprise Architect. Specifically, the client reveals the plaintext OAuth2 client secret. The desktop client decodes this secret and uses it in its plaintext form to exchange for access and ID tokens during the OpenID authentication flow.

Impact Analysis

Because the OAuth2 client secret is exposed in plaintext, an attacker who gains access to this secret could potentially impersonate the client and obtain access and ID tokens. This could lead to unauthorized access to protected resources or user data.
