CVE-2023-0347Network attack vector

Cloud device identification via MAC and IP

Published Mar 13, 2023 · Updated Jan 16, 2025

Information exposure in Akuvox E11 111.30.2.19 and earlier allows remote attackers to identify a device on the Akuvox cloud. The cloud identification workflow treats the device's MAC address together with its IP address as sufficient identifying data, without anonymizing the identifiers or protecting their transport with HTTPS. Network access and both identifiers are required; the published impact is limited to correlating an E11 with its cloud identity.
