CVE-2025-57072Network attack vector

Unauthenticated service interruption via staticRouteGateway stack overflow

Published Sep 9, 2025 · Updated Sep 9, 2025

Stack-based buffer overflow in Tenda G3 3.0br_V15.11.0.17 allows remote attackers to interrupt service via a crafted request. The overflow is localized to the staticRouteGateway parameter in formSetStaticRoute; public materials do not disclose the unsafe memory operation or missing bounds check. No authentication or user interaction is required; malformed static-route input can interrupt the router, although the record does not distinguish a crash from a hang or reboot.
