CVE-2022-30562Network attack vector

User redirection via trusted Host header

Published Jun 28, 2022 · Updated Aug 3, 2024

Open redirect in Dahua IPC-HDBW2XXX, IPC-HFW2XXX, and ASI7XXXX devices allows man-in-the-middle attackers to redirect users. The HTTPS request handler trusts a modified Host header and returns a 302 response pointing the browser to an attacker-controlled URL. HTTPS must be enabled, the attacker must alter an in-transit request, and firmware must predate the applicable build-time cutoff; the reported consequence is redirection, not device takeover.
