D-Link WBR-1310 – Authentication Bypass
# Exploit Title: D-Link WBR-1310 Authentication Bypass Vulnerability # Shodan Dork: Embedded HTTP Server 2.00 # Date: 22-Dec-2010 # Author: Craig Heffner, /dev/ttyS0 # Software Link: http://www.dlink.com/products/?pid=474 # Version: 2.00 # Tested on: WBR-1301, firmware version 2.00 The CGI scripts in the D-Link WBR-1310 (firmware v.2.00) do not validate authentication credentials. Administrative settings can be changed by sending the appropriate HTTP request directly to a CGI script without authenticating to the device. The following request will change the administrative password to 'hacked' and enable remote administration on port 8080: http://192.168.0.1/tools_admin.cgi?admname=admin&admPass1=hacked&admPass2=hacked&username=user&userPass1=WDB8WvbXdHtZyM8&userPass2=WDB8WvbXdHtZyM8&hip1=*&hport=8080&hEnable=1 Even if remote administration is not enabled, any Web page that any internal user browses to can change the administrator password and enable remote administration via a hidden image tag embedded in the Web page. No Javascript required. Newer versions of the WBR-1310 firmware are not vulnerable, but since version 2.00 is the default firmware, most WBR-1310 routers are still running it.
