CVE-2024-52711Public exploit

Authenticated service crash via unbounded IP copy

Published Nov 19, 2024 · Updated Nov 22, 2024

Buffer overflow in D-Link DI-8100 16.07.26A1 allows remote authenticated users to crash its web service via a crafted IP parameter. The ip_position_asp function uses sprintf to copy the attacker-controlled ip parameter into stack variable v5 without a length check, overflowing the destination buffer. Exploitation requires an authenticated session from an adjacent network, and the demonstrated consequence is a web-service crash rather than data disclosure or modification.
