CVE-2013-6343: Multiple buffer overflows in web.c in httpd on the ASUS RT-N56U and RT-AC66U routers with firmware 3.0.0.4....

Security readout for executives and security teams

This CVE affects specific ASUS router firmware and can let a remote attacker run code through the router’s web service. For executives, the business risk is loss of control of edge network equipment. The source bundle does not prove active exploitation, but it includes public exploit references. Exposure is limited by the bundle to ASUS RT-N56U and RT-AC66U routers running firmware 3.0.0.4.374_979. Risk increases if the router web interface is reachable from untrusted networks or the internet. Prioritize remediation for any exposed affected router because compromise could give attackers control over network edge infrastructure. If devices are internal-only, still plan replacement or firmware validation because public exploit material exists. Mitigation focus: Identify any ASUS RT-N56U or RT-AC66U devices running firmware 3.0.0.4.374_979.; Check ASUS or carrier vendor guidance for fixed firmware or replacement direction.; Remove untrusted access to the router web management interface..
