CVE-2023-4465Known exploitationPublic exploitNetwork attack vector

Administrator persistence via unchecked configuration import

Published Dec 29, 2023 · Updated Aug 2, 2024

Unverified password change in Poly phone configuration import allows remote authenticated users to replace the administrator password. The importer applies device.auth.localAdminPassword from an uploaded XML configuration without checking the current password. An enabled web server and an active administrator session are required, and the change preserves device access after that session expires.
