Unauthenticated telnet access via hard-coded credentials
Published Mar 28, 2024 · Updated Jan 14, 2025
Hard-coded credentials in all versions of NEC Aterm routers allow unauthenticated attackers on the LAN to access the telnet service. An unnecessary account retained by a specific router function accepts a fixed credential, enabling unauthorized telnet login. The vendor has not disclosed the account or function name; reachability is limited to the LAN, and the documented consequence is sensitive-information access.
