CVE-2025-8077 is a critical security vulnerability identified in SUSE's NeuVector product, specifically affecting versions up to and including 5.4.5. The vulnerability arises from the use of a fixed default password for the built-in 'admin' account. This default password is a static string that is not randomized or unique per deployment. If administrators do not change this default password immediately after deploying NeuVector, any workload within the cluster that has network access can authenticate using these default credentials. Once authenticated, an attacker can obtain an authentication token that grants full access to NeuVector's API. This access allows the attacker to perform any operation available through the API, including potentially modifying security policies, disabling protections, or extracting sensitive information about container workloads and network traffic. The vulnerability is classified under CWE-1393, which relates to the use of default passwords, a common and dangerous security misconfiguration. The CVSS v3.1 base score is 9.8, reflecting the vulnerability's critical nature due to its network attack vector, no required privileges or user interaction, and its impact on confidentiality, integrity, and availability. NeuVector is a container security platform widely used to monitor and protect Kubernetes environments, making this vulnerability particularly impactful in cloud-native and containerized infrastructures. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the urgency for administrators to change default credentials immediately and implement compensating controls.

For European organizations, the impact of CVE-2025-8077 is significant, especially those relying on Kubernetes and containerized workloads secured by NeuVector. Exploitation could lead to full compromise of container security controls, enabling attackers to bypass network segmentation, disable runtime protections, and access sensitive application data. This could result in data breaches, lateral movement within the cluster, and disruption of critical services. Given the increasing adoption of cloud-native technologies across European industries such as finance, manufacturing, and telecommunications, the vulnerability poses a substantial risk to confidentiality, integrity, and availability of business-critical applications. Additionally, regulatory frameworks like GDPR impose strict data protection requirements; a breach facilitated by this vulnerability could lead to severe compliance penalties and reputational damage. The fact that exploitation requires no privileges or user interaction increases the risk of automated attacks spreading rapidly within vulnerable clusters.

Immediate mitigation steps include changing the default 'admin' password in NeuVector deployments before any network exposure occurs. Organizations should enforce policies that prevent the use of default credentials and implement automated checks to detect unchanged default passwords. Network segmentation should be applied to limit access to NeuVector management interfaces only to trusted administrative hosts. Employing role-based access control (RBAC) and multi-factor authentication (MFA) where supported can further reduce risk. Monitoring API access logs for unusual authentication attempts or token usage can help detect exploitation attempts early. Since no patch is currently linked, organizations should stay alert for official updates from SUSE and plan prompt patch deployment once available. Additionally, consider deploying runtime security tools that can detect anomalous container behavior as a compensating control. Regular security audits and penetration testing focused on container security configurations will help identify similar misconfigurations proactively.
