CVE-2024-0925Public exploitNetwork attack vector

Service crash via unbounded virtual-server list parsing

Published Jan 26, 2024 · Updated Jun 17, 2025

Stack-based buffer overflow in Tenda AC10U firmware 15.03.06.49_multi_TDE01 allows remote attackers to crash the router via a crafted list parameter. The formSetVirtualSer handler passes list to save_virtualser_data without a length check, where unbounded sscanf fields overflow fixed-size stack buffers. A network request to /goform/SetVirtualServerCfg reaches the faulty parser without user interaction; the published proof of concept demonstrates an oversized request, not code execution.
