common.c in infosvr in ASUS WRT firmware 3.0.0.4.3761071, 3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U, RT-N66U, and other routers, does not properly check the MAC address for a request, which allows remote attackers to bypass authentication and execute arbitrary commands via a NETCMDIDMANUCMD packet to UDP port 9999. NOTE: this issue was incorrectly mapped to CVE-2014-10000, but that ID is invalid due to its use as an example of the 2014 CVE ID syntax change.

AdvancedSystemContent.asp in the ASUS RT series routers with firmware before 3.0.0.4.374.5517, when an administrator session is active, allows remote authenticated users to obtain the administrator user name and password by reading the source code.

Cross-site scripting (XSS) vulnerability in AdvancedWirelessContent.asp in ASUS RT-AC68U and other RT series routers with firmware before 3.0.0.4.374.5047 allows remote attackers to inject arbitrary web script or HTML via the currentpage parameter to apply.cgi.
