Certain NETGEAR devices are affected by incorrect configuration of security settings. This affects D6220 before 1.0.0.32, D6400 before 1.0.0.66, D8500 before 1.0.3.35, DGN2200Bv4 before 1.0.0.94, DGN2200v4 before 1.0.0.94, R6250 before 1.0.4.14, R6300v2 before 1.0.4.18, R6400 before 1.01.32, R6400v2 before 1.0.2.44, R6700 before 1.0.1.36, R6900 before 1.0.1.30, R6900P before 1.3.0.8, R7000 before 1.0.9.14, R7000P before 1.3.0.8, R7100LG before 1.0.0.34, R7900 before 1.0.2.4, R8000 before 1.0.4.2, WN2500RPv2 before 1.0.1.50, WNDR3400v3 before 1.0.1.14, and WNDR4000 before 1.0.2.10.
Certain NETGEAR devices allow remote attackers to disable all authentication requirements by visiting genieDisableLanChanged.cgi. The attacker can then, for example, visit MNUaccessPasswordrecovered.html to obtain a valid new admin password. This affects AC1450, D8500, DC112A, JNDR3000, LG2200D, R4500, R6200, R6200V2, R6250, R6300, R6300v2, R6400, R6700, R6900P, R6900, R7000P, R7000, R7100LG, R7300, R7900, R8000, R8300, R8500, WGR614v10, WN2500RPv2, WNDR3400v2, WNDR3700v3, WNDR4000, WNDR4500, WNDR4500v2, WNR1000, WNR1000v3, WNR3500L, and WNR3500L.
An issue was discovered on NETGEAR R8500, R8300, R7000, R6400, R7300, R7100LG, R6300v2, WNDR3400v3, WNR3500Lv2, R6250, R6700, R6900, and R8000 devices. They are prone to password disclosure via simple crafted requests to the web management server. The bug is exploitable remotely if the remote management option is set, and can also be exploited given access to the router over LAN or WLAN. When trying to access the web panel, a user is asked to authenticate; if the authentication is canceled and password recovery is not enabled, the user is redirected to a page that exposes a password recovery token. If a user supplies the correct token to the page /passwordrecovered.cgi?id=TOKEN (and password recovery is not enabled), they will receive the admin password for the router. If password recovery is set the exploit will fail, as it will ask the user for the recovery questions that were previously set when enabling that feature. This is persistent (even after disabling the recovery option, the exploit will fail) because the router will ask for the security questions.
