CVE-2014-9583
HighSummary
The ASUS WRT firmware versions 3.0.0.4.376_1071, 3.0.0.376.2524-g0013f52, and others, used in RT-AC66U, RT-N66U, and other routers, have an issue with improper MAC address checking in requests. This allows remote attackers to bypass authentication and execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port 9999.
Risk Assessment
The organization may be exposed to remote attacks that allow unauthorized command execution, potentially leading to device takeover and data leakage.
Recommendation
It is recommended to update the router firmware to the latest version that includes security patches and to monitor traffic on UDP port 9999.
