CVE-2023-0861 [High] | Code Injection in Netmodule Router Software

NetModule NSRW web administration interface executes an OS command constructed with unsanitized user input. A successful exploit could allow an authenticated user to execute arbitrary commands with elevated privileges. This issue affects NSRW: from 4.3.0.0 before 4.3.0.119, from 4.4.0.0 before 4.4.0.118, from 4.6.0.0 before 4.6.0.105, from 4.7.0.0 before 4.7.0.103.
