CVE-2023-0354Network attack vector

Unauthenticated configuration and packet-capture access via unprotected routes

Published Mar 13, 2023 · Updated Jan 16, 2025

Missing authentication in the Akuvox E11 web server through 111.30.2.19 allows remote attackers to read configuration data and packet captures. FCGI routes serve device configuration, start network sniffing, and expose generated configuration archives and packet-capture files without checking a session. Network reachability to the device is sufficient; the exposed data can include cloud tokens, service credentials, images, and logs carried in cleartext.
