CVE-2022-30563Network attack vector

Authentication bypass via replayed ONVIF login packets

Published Jun 28, 2022 · Updated Aug 3, 2024

Authentication replay in Dahua Technology IPC-HDBW2XXX, IPC-HFW2XXX, and ASI7XXXX devices allows man-in-the-middle attackers to log in via ONVIF. The ONVIF authentication path accepts a captured successful login request again without rejecting its reused authentication data. Interception of a legitimate user's ONVIF login is required, after which the attacker can issue authenticated requests within that user's device permissions.
