EUVD-2025-29463

Comprehensive Technical Analysis of EUVD-2025-29463

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-29463 affects NeuVector versions up to and including 5.4.5. The issue arises from the use of a fixed string as the default password for the built-in admin account. This default password, if not changed immediately after deployment, can be exploited by any workload with network access within the cluster to obtain an authentication token. This token can then be used to perform any operation via NeuVector APIs.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS:3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity, no privileges required, no user interaction needed) and the severe impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Network Access: Any workload within the cluster that has network access can attempt to use the default credentials.
2. Default Credentials: The fixed string used as the default password for the admin account.

Exploitation Methods:

1. Credential Stuffing: Attackers can use the default credentials to authenticate as the admin user.
2. Token Theft: Once authenticated, attackers can obtain an authentication token.
3. API Abuse: Using the stolen token, attackers can perform any operation via NeuVector APIs, including but not limited to:
   • Accessing sensitive data
   • Modifying configurations
   • Deleting resources
   • Executing arbitrary commands

3. Affected Systems and Software Versions

Affected Software:

• NeuVector versions up to and including 5.4.5

Affected Systems:

• Any system or cluster running the affected versions of NeuVector.

4. Recommended Mitigation Strategies

1. Immediate Password Change: Ensure that the default password for the admin account is changed immediately after deployment.
2. Patch Management: Upgrade to NeuVector version 5.4.6 or later, which addresses this vulnerability.
3. Network Segmentation: Implement strict network segmentation to limit access to the NeuVector management interface.
4. Monitoring and Logging: Enable comprehensive monitoring and logging to detect any unauthorized access attempts.
5. Access Controls: Implement strong access controls and multi-factor authentication (MFA) for administrative accounts.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations using NeuVector within the European Union. Given the critical nature of the vulnerability, it could lead to:

• Unauthorized access to sensitive data
• Compromise of critical infrastructure
