# ONVIF device service on E3 leaks device identifiers and user account list

The ONVIF device service on the E3 answers certain informational requests without any login. A remote unauthenticated party can read detailed device identifiers and the configured user accounts with their privilege levels, which helps target credential attacks.

_Summary, check and fix written by a model from the sources; labelled as such._
