By sending requests to specific endpoints, such as /api/v1/databases, without an Authorization header or with invalid/tampered JWT tokens, attackers can bypass security controls and retrieve stored database configuration details.</p>
<h2 id="impact">Impact</h2>
<p>Successful exploitation allows unauthenticated remote attackers to exfiltrate sensitive information from the application, specifically database host addresses, usernames, and passwords stored within the system. The CVSS v3.1 base score for this vulnerability is 7.5.</p>
<h2 id="recommendation">Recommendation</h2>
<ol>
<li>Identify all instances of OpsTree REMS version 1.0.0 or earlier within the environment.</li>
<li>Implement network segmentation or access control lists (ACLs) to restrict access to the Governance API endpoints (e.g., /api/v1/databases) to trusted administrative IP addresses until a patch is applied.</li>
<li>Monitor server-side web application logs for HTTP requests to /api/v1/databases that lack valid Authorization headers or contain suspicious/malformed tokens.</li>
</ol>

Attackers can send a POST /api/v1/user/login/ request for the admin account with an invalid password and the is_local_auth field set to true to bypass authentication.</p>
<h2 id="impact">Impact</h2>
<p>Successful exploitation allows an unauthenticated attacker to obtain a valid JWT for an administrative account, resulting in SuperUser administrative access.</p>
<h2 id="recommendation">Recommendation</h2>
<p>Monitor logs for the POST /api/v1/user/login/ request pattern where the client-controlled is_local_auth field is set to true.</p>
