The precise impact of exploitation is not explicitly stated, but a buffer overflow of this nature typically allows code execution with the privileges of the web-server process."}}}}, "created": "2026-04-08T19:59:46.418374+00:00", "title": "Buffer overflow in D-Link DI-8003 /user_group.asp endpoint", "updated": "2026-04-14T16:40:24.109514+00:00", "vendors": ["dlink", "dlink$PRODUCT$di-8003"]}
