CVE-2023-0352Network attack vector

Administrator takeover via unauthenticated password recovery

Published Mar 13, 2023 · Updated Jan 16, 2025

Weak password recovery in Akuvox E11 111.30.2.19 and earlier allows remote attackers to obtain the device key and reset its password. The password recovery webpage serves the device key file without authentication and accepts that key to restore the password to its default. Network access to the web interface is sufficient, exposing device administration under the known default credentials.
