VAR-202510-0030

Vulnerability from variot - Updated: 2025-11-20 23:17

A flaw has been found in D-Link DI-7100G C1 up to 20250928. This vulnerability affects the function sub_4C0990 of the file /webchat/login.cgi of the component jhttpd. Executing manipulation of the argument openid can lead to buffer overflow. It is possible to launch the attack remotely. The exploit has been published and may be used. The D-Link DI-7100G C1 is an enterprise-class router designed primarily for small and medium-sized businesses.

The D-Link DI-7100G C1 suffers from a buffer overflow vulnerability. This vulnerability stems from a failure to properly validate the length of input data in the openid parameter in the /webchat/login.cgi file. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
