How the Exploit Works

The exploit leverages a use-after-free vulnerability in the Remote Desktop Gateway Service. 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.

Conceptual Example Code

Here’s a conceptual example illustrating how this vulnerability might be exploited:

POST /rdg/service/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "<CODE TO EXPLOIT USE-AFTER-FREE VULNERABILITY>" }

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.

Mitigation Guidance

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.
