Unitree Go1 | <= Go1_2022_05_11 How the Exploit Works

The exploit takes advantage of hardcoded authentication credentials in plaintext in the firmware of the Unitree Go1. A malicious actor could discover these credentials and use them to gain unauthorized access to the system. Once in, they can manipulate the system, potentially gaining control over data and resources.

Conceptual Example Code

Let’s consider a conceptual scenario where the attacker sends a network request to the system, exploiting the vulnerability.

GET /login HTTP/1.1
Host: unitree.example.com
Authorization: Basic [hardcoded plaintext credentials]

The above example showcases how the hardcoded plaintext credentials could be used in the HTTP authorization field to gain access to the system.

Mitigation Guidelines

To mitigate the risk posed by CVE-2025-45466, it is recommended to apply the vendor patch as soon as possible. However, if for some reason the patch cannot be applied immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) could serve as a temporary mitigation measure. These systems can help detect and prevent unauthorized access attempts, thus reducing the risk of exploitation. Additionally, it is advised to regularly update all systems and applications to the latest versions, as they often include security patches for known vulnerabilities.
