CVE-2024-0532Public exploitNetwork attack vector

Code execution via unchecked Wi-Fi crypto string copy

Published Jan 15, 2024 · Updated May 14, 2025

Stack-based buffer overflow in the Tenda A15 15.13.07.13 web interface allows remote authenticated users to execute code or crash it. The /goform/WifiExtraSet handler retrieves a Wi-Fi crypto parameter with websGetVar and passes it to a repeat-setting routine that copies the value with strcpy without checking its length. High-privilege management access is required; successful exploitation can corrupt memory, crash the service, or execute code on the appliance.
