What is the CVSS score of EUVD-2025-209276?

EUVD-2025-209276 has a CVSS 3.1 base score of 7.5 (High). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N. EPSS exploitation probability: 0.0%.

How to fix or mitigate EUVD-2025-209276?

Within 24 hours: Identify all GenieACS instances running version 1.2.13 and assess network exposure of the NBI API endpoint. Within 7 days: Implement network-level access controls (firewall rules, WAF) to restrict NBI API access to authorized management networks only, and evaluate upgrade feasibility to versions beyond 1.2.13. Within 30 days: Complete migration to a patched GenieACS version or deploy compensating controls if upgrade is not immediately possible; conduct forensic review of NBI API logs for unauthorized access attempts.

HIGH 7.5

DescriptionCVE.org

In GenieACS 1.2.13, an unauthenticated access vulnerability exists in the NBI API endpoint.

AnalysisAI

Unauthenticated remote information disclosure in GenieACS 1.2.13 NBI API allows network-based attackers to read sensitive configuration data without authentication. The CVSS vector confirms zero authentication requirements (PR:N), enabling attackers to directly access the NBI API endpoint and exfiltrate high-confidentiality information. Publicly available exploit code exists. Attack complexity is low with no user interaction required. EPSS indicates low observed exploitation activity.

Technical ContextAI

Root cause is improper access control (CWE-284) on the NBI (Northbound Interface) API endpoint. The API fails to enforce authentication checks, accepting unauthenticated network requests. This allows direct HTTP/HTTPS access to API functions designed for authenticated device management operations, exposing configuration data and potentially customer premises equipment details.

RemediationAI

No vendor-released patch identified at time of analysis. Immediately restrict network access to the NBI API endpoint using firewall rules, reverse proxy authentication, or IP allowlisting to trusted management networks only. Monitor GenieACS GitHub repository (https://github.com/genieacs/genieacs/) for security advisories and version updates beyond 1.2.13. Implement API gateway with mandatory authentication. Conduct access log review for unauthorized NBI API connections. Consider temporarily disabling the NBI API if not operationally required until patch availability is confirmed.
