CVE-2022-27644
Estado: ModificadaAlta (8.8)—
This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of NETGEAR R6700v3 1.0.4.120_10.0.91 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloading of files via 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-15797.
