CVE-2025-0355Network attack vector

Wi-Fi password disclosure via unauthenticated LAN access

Published Jan 15, 2025 · Updated Jan 21, 2025

Missing authentication in NEC Aterm router firmware allows remote attackers on the LAN to read the configured Wi-Fi password. NEC has not disclosed the request handler or endpoint that returns the credential without verifying an authenticated management session. An attacker must reach the router from its LAN side; the vendor states that WAN-side attacks over the Internet are not possible, and no integrity or availability impact is reported.
