Vulnerability from variot - Updated: 2025-11-28 23:14

A vulnerability has been found in D-Link DI-7100G C1 up to 20250928. This issue affects the function sub_4BD4F8 of the file /webchat/hi_block.asp of the component jhttpd. The manipulation of the argument popupId leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. D-Link Corporation of DI-7100G C1 The firmware contains a buffer error vulnerability and a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. The D-Link DI-7100G C1 is an enterprise-class router designed primarily for small and medium-sized businesses. This vulnerability stems from the failure of the popupId parameter in the /webchat/hi_block.asp file to properly validate the length of input data. An attacker could exploit this vulnerability to execute arbitrary code or cause a denial of service
