What is CVE-2023-27356?

A command injection vulnerability has been identified in NETGEAR RAX30 routers, enabling network-adjacent attackers to execute arbitrary code. The flaw is associated with the 'logCtrl' action, stemming from inadequate validation of user-supplied strings prior to executing system calls.
