CVE-2025-8077
📋 TL;DR
NeuVector container security platform versions up to 5.4.5 use a hardcoded default password for the built-in admin account. If not changed after deployment, any workload within the cluster can use these credentials to obtain authentication tokens and perform any operation via NeuVector APIs. This affects all NeuVector deployments with default configurations.

⚠️ Risk & Real-World Impact
Worst Case
Full compromise of NeuVector security controls, allowing attackers to disable security policies, exfiltrate sensitive container data, manipulate network rules, and potentially pivot to other cluster resources.
Likely Case
Attackers with internal cluster access use default credentials to gain administrative control over NeuVector, disabling security monitoring and modifying policies to bypass container security controls.
If Mitigated
No impact if the default password was changed during initial deployment as recommended by NeuVector documentation.
🎯 Exploit Status
Exploitation requires network access within the cluster and knowledge of the default credentials. The vulnerability is simple to exploit once an attacker gains access to any workload in the cluster.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: NeuVector 5.4.6 and later
Vendor Advisory: https://github.com/neuvector/neuvector/security/advisories/GHSA-8pxw-9c75-6w56
Restart Required: Yes
Instructions:
1. Upgrade NeuVector to version 5.4.6 or later. 2. Ensure all NeuVector components (controller, enforcer, scanner) are restarted. 3. Verify the admin password has been changed from default.
🔧 Temporary Workarounds
Change Admin Password Immediately
allChange the default admin password to a strong, unique password even if you cannot immediately patch.
kubectl exec -n neuvector deployment/neuvector-controller-pod -- nvctl user admin --set-password 'NEW_STRONG_PASSWORD'
Restrict Network Access
allImplement network policies to restrict access to NeuVector API endpoints only to authorized management systems.
🧯 If You Can't Patch
- Immediately change the default admin password using NeuVector's password change functionality
- Implement strict network segmentation and Kubernetes Network Policies to limit which pods can communicate with NeuVector API endpoints
🔍 How to Verify
Check if Vulnerable:
Check if NeuVector version is 5.4.5 or earlier and verify if default admin password was changed by attempting authentication with known default credentials (not recommended in production).Check Version:
kubectl get pods -n neuvector -o jsonpath="{.items[*].spec.containers[*].image}" | grep -o 'neuvector:[0-9.]*'Verify Fix Applied:
Verify NeuVector version is 5.4.6 or later using 'kubectl get pods -n neuvector -o jsonpath="{.items[*].spec.containers[*].image}"' and confirm the admin password has been changed from default.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful authentication from unexpected sources
- Administrative API calls from non-management IP addresses or service accounts
SIEM Query:
source="neuvector" AND (event="authentication" AND result="success" AND user="admin") AND NOT source_ip IN [management_ips]
