CVE-2025-22940Public exploitNetwork attack vector

Admin account takeover via unauthenticated password reset

Published Mar 31, 2025 · Updated Aug 18, 2025

Incorrect access control in the web interface of ADTRAN 411 ONT L80.00.0011.M2 allows remote attackers to set the admin password. The web server accepts an administrative password-change operation without enforcing authentication or the account's authorization boundary. Network access to the device's HTTP service is sufficient, and exploitation grants control of the administrator credential without interrupting service.
