CVE-2025-29361Public exploitNetwork attack vector

Unauthenticated denial of service via oversized list parameter

Published Mar 13, 2025 · Updated Mar 19, 2025

A buffer overflow in Tenda RX3 firmware 16.03.13.11_multi_TDE01 allows remote attackers to interrupt service via a crafted packet. The /goform/SetVirtualServerCfg handler copies the attacker-controlled list parameter into a fixed-size buffer without validating its length. The request needs no authentication or user interaction, and the published impact is limited to device availability.
