Unauthenticated code execution via oversized fn parameter
Published Oct 16, 2023 · Updated Aug 2, 2024
A buffer overflow in seven D-Link DI-7xxx router models allows remote attackers to execute arbitrary code through a crafted fn parameter. The tgfile.htm handler writes an oversized fn value beyond its destination buffer, producing an out-of-bounds write. No authentication or user interaction is required; successful exploitation runs attacker-controlled code on the router.
