ASUS RT-AC68U, RT-AC66R, RT-AC66U, RT-AC56R, RT-AC56U, RT-N66R, RT-N66U, RT-N56R, RT-N56U, and possibly other RT-series routers before firmware 3.0.0.4.376.x do not verify the integrity of firmware (1) update information or (2) downloaded updates, which allows man-in-the-middle (MITM) attackers to execute arbitrary code via a crafted image.

Cross-site scripting (XSS) vulnerability in Advanced_Wireless_Content.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 current_page parameter to apply.cgi.

common.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071, 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 NET_CMD_ID_MANU_CMD 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.

The Network Analysis tab (Main_Analysis_Content.asp) in the ASUS RT-AC68U and other RT series routers with firmware before 3.0.0.4.374.5047 allows remote authenticated users to execute arbitrary commands via shell metacharacters in the Target field (destIP parameter).

Advanced_System_Content.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.

busybox: insecure directory permissions in /dev

util-linux/mdev.c in BusyBox before 1.21.0 uses 0777 permissions for parent directories when creating nested directories under /dev/, which allows local users to have unknown impact and attack vectors.

busybox: udhcpc insufficient checking of DHCP options

The DHCP client (udhcpc) in BusyBox before 1.20.0 allows remote DHCP servers to execute arbitrary commands via shell metacharacters in the (1) HOST_NAME, (2) DOMAIN_NAME, (3) NIS_DOMAIN, and (4) TFTP_SERVER_NAME host name options.
