Executive Summary

This vulnerability exists in the D-Link DIR-513 device, specifically in the function formSetRoute within the POST Request Handler component. It is caused by improper handling of the argument curTime, which leads to a buffer overflow. This flaw can be exploited remotely, allowing an attacker to potentially execute arbitrary code or cause a denial of service.

The affected products are no longer supported by the maintainer, and the exploit for this vulnerability is publicly available.

Impact Analysis

Exploitation of this vulnerability can lead to severe impacts including remote code execution, denial of service, or unauthorized control over the affected device. Since the vulnerability involves a buffer overflow, an attacker could manipulate the device's behavior, potentially compromising network security or disrupting services.

Because the device is no longer supported, no official patches or fixes are available, increasing the risk of exploitation.
