CVE-2023-40480: Netgear rax30 firmware os command injection vulnerability

Netgear · Rax30 Firmware

NETGEAR RAX30 DHCP Server Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR RAX30 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the DHCP server. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19705.
