CVE-2023-2378Network attack vector

Authenticated command injection via suffix-rate-up argument

Published Apr 28, 2023 · Updated Jul 9, 2026

Command injection in Ubiquiti Inc. EdgeRouter X 2.0.9-hotfix.0 through 2.0.9-hotfix.6 allows remote authenticated users to execute commands. An undisclosed Web Management Interface function passes the suffix-rate-up argument into a command without adequate neutralization. Administrative authentication is required, and Ubiquiti disputes the issue because it does not treat post-authentication behavior as a vulnerability.
