CVE-2025-1895Network attack vector

Authenticated service interruption via oversized deviceList input

Published Mar 4, 2025 · Updated Mar 4, 2025

Stack-based buffer overflow in Tenda TX3 16.03.13.11_multi allows remote authenticated users to interrupt routing service via deviceList input. The setMacFilterCfg HTTP handler accepts an oversized deviceList value without enforcing the destination stack buffer's bounds; the public record does not identify the exact copy routine. Access to the router management interface and valid credentials are required, and the documented consequence is a device or httpd crash rather than data disclosure or modification.
