Overview
The cybersecurity world is once again under threat due to a severe vulnerability, CVE-2025-8077. This vulnerability has been identified in NeuVector versions up to and including 5.4.5 and pertains to the use of a default password for the built-in `admin` account. If left unchanged after deployment, this vulnerability could potentially lead to system compromise or data leakage. This vulnerability is of particular concern to businesses or industries that rely heavily on NeuVector for their operational needs, as unauthorized access through this vulnerability could have devastating effects on their systems and data.

How the Exploit Works
The vulnerability CVE-2025-8077 arises from the use of a fixed string as the default password for the built-in `admin` account in NeuVector. If this password is not changed immediately after deployment, any workload within the cluster with network access can use these default credentials to obtain an authentication token. This token can then be used to perform any operation via the NeuVector APIs, thereby potentially compromising the system or causing data leakage.
Conceptual Example Code
Below is a conceptual example of how this vulnerability might be exploited using a simple HTTP request:
POST /neuvector/api/v2/auth/login HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"username": "admin",
"password": "defaultpassword"
}In this example, an attacker uses the default `admin` credentials to authenticate against the NeuVector API. Once authenticated, the attacker could potentially perform any operation via the NeuVector APIs, leading to system compromise or data leakage.
To protect against this vulnerability, users are urged to change the default `admin` password immediately after deployment. As a temporary mitigation, a WAF/IDS could be used, or you could apply the vendor patch as soon as it becomes available.
