D-Link DIR-300NRUB5 Firmware 1.2.94 Cross Site Request Forgery

ID: 88652
CVE: None
Download vulnerable application: None
Hello list!

There are Abuse of Functionality, Brute Force and Cross-Site Request Forgery
vulnerabilities in D-Link DIR-300.

Affected products:

Vulnerable is the next model: D-Link DIR-300NRUB5, Firmware 1.2.94. All
previous versions also must be vulnerable.


Abuse of Functionality (WASC-42):

Admin's login is persistent: admin. Which simplify BF and CSRF attacks.

Brute Force (WASC-11):


No protection from BF attacks. If there is no Path Traversal vulnerability
in this device to get admin's password, then it's possible to pick it up.

Even I found DIR-300 with firmware version from 2009, where there was a
captcha (that can be turned on/off in the settings), but there was no
captcha in new firmware.

Cross-Site Request Forgery (WASC-09):

Change admin's password:
