Description
A vulnerability was found in D-Link DI-8100 16.07.26A1. This affects the function tgfile_htm of the file tgfile.htm of the component CGI Endpoint. The manipulation of the argument fn results in buffer overflow. The attack can be executed remotely. The exploit has been made public and could be used.
A stack-based buffer overflow vulnerability has been identified in the D-Link DI-8100 router running firmware version 16.07.26A1. The issue arises in the 'tgfile_htm' function of the 'tgfile.htm' CGI endpoint, where user-supplied input in the 'fn' parameter is improperly handled, allowing for buffer overflow. This vulnerability can be exploited remotely, potentially leading to a denial-of-service condition by crashing the web server process or causing the device to reboot. Additionally, remote code execution cannot be ruled out.
