CVE-2022-45337Public exploitNetwork attack vector

Service interruption via unchecked list parameter

Published Nov 30, 2022 · Updated Apr 24, 2025

Stack overflow in Tenda TX9 Pro 22.03.02.10 allows remote attackers to interrupt service through a crafted SetIpMacBind request. The firmware's sub_42EFF8 handler reads the list parameter from the HTTP request, and sub_42EDE4 copies it into local stack buffer v18 without a length check. An oversized list value overflows the buffer; the published artifact demonstrates denial of service but does not establish code execution or data access.
