Memory corruption via oversized ip6addr filter input
Published Sep 13, 2026 · Updated Sep 13, 2026
Buffer overflow in the boa formFilter handler in TOTOLINK A3002MU Hh-B20211125.1046 allows remote attackers to corrupt memory. The /boafrm/formFilter endpoint mishandles an attacker-controlled ip6addr value and writes beyond its intended buffer. The request reaches the router's boa web-management component over the network; public records do not disclose whether exploitation is limited to a crash or permits code execution.
