CVE-2025-25453Public exploitNetwork attack vector

Web-service crash via unchecked serviceName2 stack copy

Published Apr 15, 2025 · Updated Apr 16, 2025

A stack buffer overflow in AdvSetMacMtuWan in Tenda AC10 firmware 16.03.10.20 allows remote authenticated users to crash the web service. The handler copies an oversized serviceName2 form value into a fixed-size stack buffer without a length check, corrupting execution state. CISA assesses exploitation as requiring low privileges, user interaction, and high attack complexity; code execution for this input is not publicly verified.
