Service interruption via unchecked list1 copy

Published Mar 28, 2024 · Updated Oct 28, 2024

Stack overflow in Tenda FH1203 firmware 2.0.1.6 allows remote attackers to interrupt service via a crafted list1 parameter. The fromDhcpListClient handler copies list1 data into a fixed-size stack buffer without checking its length. No privileges or user interaction are required, and the reported consequence is limited to availability rather than data disclosure or modification.
