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.
An exploitable denial-of-service vulnerability exists in the session handling functionality of the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) HTTP server. An HTTP request with an empty User-Agent string sent to a page requiring authentication can cause a null pointer dereference, resulting in the HTTP service crashing. An unauthenticated attacker can send a specially crafted HTTP request to trigger this vulnerability.
An exploitable denial-of-service vulnerability exists in the Host Access Point Daemon (hostapd) on the NETGEAR N300 (WNR2000v5 with Firmware Version V1.0.0.70) wireless router. A SOAP request sent in an invalid sequence to the <WFAWLANConfig:1#PutMessage> service can cause a null pointer dereference, resulting in the hostapd service crashing. An unauthenticated attacker can send a specially-crafted SOAP request to trigger this vulnerability.
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.
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.
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.
