When a user account is deleted by an administrator, the system fails to invalidate the active sessions and revoke associated API tokens. This means a user whose account has been deleted can still access system resources via these stale sessions and tokens, leading to potential unauthorized access to restricted functions.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1126310349\" 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>The following example presents a conceptual representation of how an HTTP request might be manipulated to exploit this vulnerability:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/restricted_function HTTP\/1.1\nHost: target.example.com\nAuthorization: Bearer &lt;stale_token&gt;\n{ &quot;user&quot;: &quot;deleted_user&quot; }<\/code><\/pre>\n<p>In this example, `<stale_token>` would be the API token still valid after the user account deletion. The server, not properly invalidating these stale tokens, will grant access to the `deleted_user` to the `restricted_function` endpoint.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview The alert pertains to a significant access control vulnerability identified in the 2024R1.0.3 version of Nagios Network Analyzer.
