VAR-202507-2480

Vulnerability from variot - Updated: 2025-08-02 23:04

A vulnerability was found in D-Link DIR-513 up to 20190831. It has been declared as critical. This vulnerability affects the function formSetWanDhcpplus of the file /goform/formSetWanDhcpplus. The manipulation of the argument curTime leads to buffer overflow. The attack can be initiated remotely. This vulnerability only affects products that are no longer supported by the maintainer. The D-Link DIR-513 is a portable wireless router featuring a slim design and ease of use. It supports IEEE 802.11n and 802.11g/b standards and offers a maximum transmission rate of 300Mbps. An attacker could exploit this vulnerability by remotely sending specially crafted data to trigger the buffer overflow, resulting in a denial of service or arbitrary code execution
