CVE-2025-2957Public exploit

Adjacent-network denial of service via HTTP null dereference

Published Mar 30, 2025 · Updated Apr 1, 2025

NULL pointer dereference in the TRENDnet TEW-411BRP+ 2.07 HTTP handler allows remote attackers to crash the router from the local network. The sub_401DB0 function in /usr/sbin/httpd dereferences a null pointer while processing a crafted HTTP request. Unauthenticated access to the local network is sufficient, and exploitation interrupts routing service without reported data disclosure or modification.
