CVE-2024-32316Public exploit

Service interruption via unbounded list1 parameter

Published Apr 17, 2024 · Updated Aug 16, 2024

Stack-based buffer overflow in Tenda AC500 firmware 2.0.1.9(1307) allows remote attackers to interrupt service over an adjacent network. The fromDhcpListClient handler for /goform/DhcpListClient fails to bound the list1 parameter before writing it to a stack buffer. No authentication or user interaction is required, and the published assessment limits the demonstrated consequence to service interruption rather than data access or modification.
