What is CVE-2020-10928?

This vulnerability enables network-adjacent attackers to execute arbitrary code on affected NETGEAR R6700 routers. The flaw arises from improper validation of user-supplied data lengths during string table file uploads, leading to uncontrolled buffer copying. This lack of stringent checks allows an attacker to run malicious code within the web server’s context, posing significant risks to network integrity. Authentication is not necessary for exploitation, making this vulnerability particularly concerning for affected users.
