→CVE-2025-46271 is an unauthenticated OS command injection affecting UNI-NMS-Lite (versions 1.0b211018 and prior), NMS-500 (all versions), and NMS-1000V (all versions); detect unauthenticated requests to NMS management interfaces that contain shell metacharacters or command-chaining sequences ↗
→No authentication is required to trigger the injection; alert on any unauthenticated HTTP/S requests to UNI-NMS-Lite, NMS-500, or NMS-1000V management endpoints that include OS command injection patterns (e.g., semicolons, pipes, backticks, $() constructs) ↗
→CVSS v4 score of 9.3 with AV:N/AC:L/AT:N/PR:N/UI:N indicates fully remote, no-auth, low-complexity exploitation; prioritize network-level blocking of external access to these NMS management interfaces ↗

·No known public exploitation has been reported at time of advisory publication; detection posture should be preventive/monitoring rather than reactive to known active campaigns ↗
