Exploit Author: Blessen Thomas
Date : 29/07/14
Vendor Homepage : http://www.dlink.com/
Software Link : N/A
Firmware version: v2.02 2013-03-13
Tested on : Windows 7
CVE : CVE-2014-3136
Type of Application : Web application
Release mode : Coordinated disclosure
Vulnerability description:
It was observed that the D-link DWR-113 wireless router is vulnerable to
denial of service attack via CSRF(Cross-Site Request Forgery) vulnerability.
An attacker could craft a malicious CSRF exploit to change the password in
the password functionality when the user(admin) is logged in to the
application ,as the user interface (admin panel) lacks the csrf token or
nonce to prevent an attacker to change the password.
As a result, as soon as the crafted malicious exploit is executed the
router is rebooted and the user could not login thus forcing to reset the
router’s device physically ,leading to a denial of service condition.
POC code (exploit) :
*Restart Router by CSRF*
