Summary

The D-Link DIR-850L devices, specifically REV. A with firmware versions up to FW114WWb07_h2ab_beta1, exhibit a significant security weakness. The vulnerability lies in the 'bind.php' file within the parental controls section, where it fails to safeguard against unauthenticated nonce-guessing attacks. This oversight enables remote attackers to manipulate the DNS configuration through a sequence of crafted requests, potentially leading to unauthorized access and control over the device's network settings.
