Certain NETGEAR devices allow unauthenticated access to critical .cgi and .htm pages via a substring ending with .jpg, such as by appending ?x=1.jpg to a URL. This affects MBR1515, MBR1516, DGN2200, DGN2200M, DGND3700, WNR2000v2, WNDR3300, WNDR3400, WNR3500, and WNR834Bv2.

CVE-2019-17137
This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of NETGEAR AC1200 R6220 Firmware version 1.1.0.86 Smart WiFi Router. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of path strings. By inserting a null byte into the path, the user can skip most authentication checks. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-8616.
CVE-2019-17049
NETGEAR SRX5308 4.3.5-3 devices allow SQL Injection, as exploited in the wild in September 2019 to add a new user account.
CVE-2019-14526
An issue was discovered on NETGEAR Nighthawk M1 (MR1100) devices before 12.06.03. The web-interface Cross-Site Request Forgery token is stored in a dynamically generated JavaScript file, and therefore can be embedded in third party pages, and re-used against the Nighthawk web interface. This entirely bypasses the intended security benefits of the use of a CSRF-protection token.
CVE-2019-14527
An issue was discovered on NETGEAR Nighthawk M1 (MR1100) devices before 12.06.03. System commands can be executed, via the web interface, after authentication.
CVE-2019-14363
A stack-based buffer overflow in the upnpd binary running on NETGEAR WNDR3400v3 routers with firmware version 1.0.1.18_1.0.63 allows an attacker to remotely execute arbitrary code via a crafted UPnP SSDP packet.
