CVE-2024-34946Public exploitNetwork attack vector

Service interruption via oversized DHCP page parameter

Published May 10, 2024 · Updated Feb 13, 2025

Stack-based buffer overflow in Tenda FH1206 1.2.0.8(8155) allows remote attackers to interrupt service via a crafted page value. The DhcpListClient handler accepts page at /goform/DhcpListClient without enforcing the stack destination's bounds, so oversized input overwrites adjacent stack memory. The management endpoint must be network-reachable; exploitation is unauthenticated but requires user interaction and is bounded to availability impact by CISA's assessment.
