An issue was discovered on PLANEX CS-W50HD devices with firmware before 030720. The device has a command-injection vulnerability in the web management UI on NAS settings page "/cgi-bin/nasset.cgi". An attacker can send a crafted HTTP POST request to execute arbitrary code. Authentication is required before executing the attack.
An issue was discovered on PLANEX CS-W50HD devices with firmware before 030720. A hardcoded credential "supervisor:dangerous" was injected into web authentication database "/.htpasswd" during booting process, which allows attackers to gain unauthorized access and control the device completely; the account can't be modified or deleted.
An issue was discovered on the PLANEX CS-QR20 1.30. A hidden and undocumented management page allows an attacker to execute arbitrary code on the device when the user is authenticated. The management page was used for debugging purposes, once you login and access the page directly (/admin/system_command.asp), you can execute any command.
The web interface on D-Link DIR-100, DIR-120, DI-624S, DI-524UP, DI-604S, DI-604UP, DI-604+, and TM-G5240 routers; Planex BRL-04R, BRL-04UR, and BRL-04CW routers; and Alpha Networks routers allows remote attackers to bypass authentication and modify settings via an xmlset_roodkcableoj28840ybtide User-Agent HTTP header, as exploited in the wild in October 2013.
