CVE-2023-45479Public exploitNetwork attack vector

Service crash via unchecked list parameter

Published Nov 29, 2023 · Updated Aug 2, 2024

Stack-based buffer overflow in Tenda AC10 firmware US_AC10V4.0si_V16.03.10.13_cn allows remote attackers to crash its service. The sub_49E098 function passes the list parameter from the /goform/SetIpMacBind handler to sscanf without length checks, overflowing the mac_addr or ip_addr stack buffer. An unauthenticated HTTP POST from a network-reachable host is sufficient to interrupt the service; the published proof of concept does not demonstrate code execution.
