CVE-2014-9583 is a critical unauthenticated command execution vulnerability in the infosvr service of ASUS WRT firmware (including versions 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and others) as used in routers such as RT-AC66U, RT-N66U, and others. The vulnerability arises from improper authentication checks in common.c, where the MAC address is not properly validated (using memcpy instead of memcmp), and a password check is present but commented out. This allows any attacker on the local network to send a specially crafted NET_CMD_ID_MANU_CMD packet to UDP port 9999 and execute arbitrary commands as root on the device.
