CVE-2025-4903Public exploitNetwork attack vector

Administrator takeover via unauthenticated password reset

Published May 19, 2025 · Updated May 19, 2025

Authentication bypass in D-Link DI-7003GV2 24.04.18D1 R(68125) allows remote attackers to reset the administrator password. The unauthenticated /H5/webgl.asp handler sub_41F4F0 saves attacker-supplied http_passwd data and invokes jhl_httpd_reset_user when exec_service is admin-restart. A single crafted HTTP request changes the administrator credential, enabling subsequent administrative access.
