Summary: JT3500V is a most advanced LTE-A Pro CAT12 indoor Wi-Fi
&amp; VoIP CPE product specially designed to enable quick and easy
LTE fixed data service deployment for residential and SOHO customers.
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: JT3500V is vulnerable to unauthenticated configuration disclosure
when direct object reference is made to the export_settings.cgi file
using an HTTP GET request. This will enable the attacker to disclose
sensitive information and help her in authentication bypass, privilege
escalation and full system access.

Tested on: GoAhead-Webs/2.5.0 PeerSec-MatrixSSL/3.1.3-OPEN
           Linux 2.6.36+ (mips)
           Mediatek APSoC SDK v4.3.1.0
