CVE-2025-12619Public exploitNetwork attack vector

Authenticated code execution via wireless-setting buffer overflow

Published Nov 3, 2025 · Updated Nov 3, 2025

Buffer overflow in Tenda A15 15.13.07.13 allows remote authenticated users to execute arbitrary code via a crafted wireless setting. The fromSetWirelessRepeat function in /goform/openNetworkGateway fails to bound the wpapsk_crypto2_4g request-body value before copying it into memory. Low-privilege access to the network-facing web interface is required; successful exploitation executes code on the repeater.
