CVE-2020-0610 is a critical remote code execution vulnerability in Microsoft Windows Remote Desktop Gateway (RD Gateway), an optional Windows Server component used to broker remote desktop access. The flaw can be triggered by an unauthenticated attacker that connects to a vulnerable RD Gateway instance using RDP-related traffic and sends specially crafted requests. Available reporting indicates exploitation occurs via the RD Gateway service, including its UDP transport path, and can result in arbitrary code execution on the target server. The issue is distinct from, but closely related to, CVE-2020-0609 and was addressed by Microsoft in the January 2020 security updates.

This repository provides a Proof-of-Concept (PoC) exploit and scanner for the Microsoft Windows Remote Desktop Gateway (RD Gateway) vulnerabilities CVE-2020-0609 and CVE-2020-0610, collectively known as 'BlueGate'. The main exploit capabilities are: - **Denial of Service (DoS) Attack**: Implemented in `dos.py`, this script sends a large number of specially crafted DTLS packets to the target's UDP port 3391, causing the RD Gateway service to crash. - **Vulnerability Scanner**: Implemented in `check.py`, this script sends a crafted DTLS packet to the target and interprets the response to determine if the service is vulnerable. The repository includes a patched version of the `pydtls` library to support DTLS operations in Python, as the original library did not build properly. The `pydtls` directory contains the full source and test suite for this library, including certificate generation scripts and test clients/servers. **Structure:** - `dos.py`: Main DoS exploit script (Python) - `check.py`: Vulnerability scanner script (Python) - `pydtls/`: Patched DTLS library (Python), with submodules for protocol handling, OpenSSL interfacing, and test scripts - `pydtls/dtls/test/`: Contains test scripts, certificates, and utilities for DTLS **Purpose:** The repository is intended for security researchers to test and demonstrate the impact of the BlueGate vulnerabilities on RD Gateway servers. It does not provide a remote code execution payload, but rather focuses on DoS and detection. The exploit is network-based, targeting UDP port 3391 on Windows Server systems running RD Gateway. **Notable findings:** - The exploit is operational and can crash vulnerable RD Gateway services. - The scanner provides a quick way to check for vulnerability. - The repository includes a full DTLS implementation, which may be useful for further research or custom exploit development.
This repository provides a proof-of-concept (PoC) exploit and scanner for the Microsoft RD Gateway vulnerabilities CVE-2020-0609 and CVE-2020-0610, known as 'BlueGate'. The main exploit is implemented in Python (BlueGate.py), with an older C++ version in the 'old' directory. The Python script can operate in two modes: 'check' (to test if a target is vulnerable) and 'dos' (to perform a Denial of Service attack). It works by sending specially crafted DTLS packets over UDP port 3391 to the target RD Gateway server, exploiting a heap out-of-bounds write vulnerability. The exploit does not provide remote code execution but demonstrates the ability to crash or destabilize the service. The repository includes documentation and build files for the C++ version, but the primary focus is the Python PoC. No hardcoded IPs or domains are present; the user supplies the target IP and (optionally) port. The exploit is intended for research and educational purposes.
