Various Netgear products that were manufactured by SerComm were found to contain a backdoor that allowed unauthorized remote access to the affected devices. Netgear, along with other companies with products manufactured by SerComm that were affected by the aforementioned backdoor, issued firmware updates for some affected products. However, it was shortly found that the updates merely hid the backdoor but did not remove it.

A backdoor also existed on the DG834 series. Any person who can access the router using a web browser, can enable "debug" mode using '[IP_ADDR]/setup.cgi?todo=debug' and then connect via telnet directly to the router's embedded Linux system as 'root', which gives unfettered access to the router's operating system via its Busybox functionality. Additionally, a 'hidden' URL '[IP_ADDR]/setup.cgi?todo=ping_test' also allows unfettered access (On a v5 model a User Name and Password are requested). There is no user option provided to disable this. On default Netgear firmware telnet access lacks password or other control; on ISP modified versions (such as Sky) a telnet password exists based on the MAC address which can be found via online websites.

On 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.
