CVE-2023-35721

Estado: AnalizadaAlta (8.8)—

NETGEAR Multiple Routers curl_post Improper Certificate Validation Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of multiple NETGEAR routers. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the update functionality, which operates over HTTPS. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-19981.
