An attacker can send specially crafted requests over the network to the Remote Desktop Gateway Service, which due to the vulnerability, incorrectly handles memory operations. As a result, the attacker can execute arbitrary code on the affected system.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1985919033\" 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>Here&#8217;s a conceptual example illustrating how this vulnerability might be exploited:<\/p>\n<pre><code class=\"\" data-line=\"\">POST \/rdg\/service\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ &quot;malicious_payload&quot;: &quot;&lt;CODE TO EXPLOIT USE-AFTER-FREE VULNERABILITY&gt;&quot; }<\/code><\/pre>\n<p>In this example, the attacker sends a POST request to the vulnerable endpoint of the Remote Desktop Gateway Service with a malicious payload designed to exploit the use-after-free vulnerability. This can result in unauthorized code execution, leading to potential system compromise and data leakage.<\/p>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To mitigate the CVE-2025-29831 vulnerability, affected entities should apply the latest vendor-provided patch for the Remote Desktop Gateway Service. If the patch cannot be applied immediately, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block exploit attempts.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview This report discusses the critical vulnerability identified as CVE-2025-29831, which targets the Remote Desktop Gateway Service.
