CVE-2025-55495Public exploitNetwork attack vector

Memory corruption via unchecked list copy

Published Aug 27, 2025 · Updated Aug 27, 2025

Buffer overflow in Tenda AC6 firmware 15.03.06.23_multi allows remote attackers to corrupt memory via a crafted list parameter. The fromSetIpMacBind handler passes list from a POST request to strcpy without a length check, writing into a 128-byte stack buffer when bindnum is 1 through 32. No privileges or user interaction are required; a reachable management endpoint permits stack-memory corruption affecting confidentiality and integrity.
