CVE-2023-38945Public exploitNetwork attack vector

Unauthenticated management access via appended URL extensions

Published Mar 6, 2024 · Updated Nov 4, 2025

Access-control bypass in Multilaser RE160 and RE160V firmware allows remote attackers to access router management via crafted URLs. The web interface routes requests ending in an accepted static-file extension, such as .js, without validating the session token required for the underlying management handler. Reachability requires access to the router interface directly or through an induced browser request; successful requests read configuration credentials or alter DNS and routing settings.
