In January 2017, various Netgear products were found to be vulnerable to an exploit that allows third-party access to the router and the internal network and to turn the router into a botnet. [31] This vulnerability occurs when an attacker can access the internal network or when remote management is enabled on the router.
The user or machine sends a request to a Network Access Server (NAS) to gain access to a particular network resource using access credentials. The credentials are passed to the NAS device via the link-layer protocol—for example, Point-to-Point Protocol (PPP) in the case of many dialup or DSL providers or posted in an HTTPS secure web form.
