Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
When an attacker uses a man-in-the-middle attack to sniff the request packets with success logging in through ONVIF, he can log in to the device by replaying the user's login packet.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a replay attack vulnerability in ONVIF authentication. An attacker positioned as a man-in-the-middle can capture valid login packets and replay them to authenticate to the device, indicating the authentication mechanism lacks replay protection such as nonces, timestamps, or session-specific tokens that invalidate captured credentials.

MitigationImplement replay protection in ONVIF authentication using nonces or timestamps, and enforce TLS encryption for all ONVIF communications to prevent packet capture.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Dahua camera models on the network
    Access your device management interface or use network scanning tools (such as ONVIF Device Manager or an NVR interface) to list all deployed IP cameras. Look for models: HDBW2431E S S2, HDBW2831E S S2, HDBW2230E S S2, HDBW2831R ZS S2, HDBW2831R ZAS S2, HDBW2531R ZS S2, HDBW2531R ZAS S2, or HDBW2531E S S2.
    Affected if Any of these eight specific Dahua camera models are present in the environment.
  2. Check firmware version on affected models
    Log into each identified camera web interface, NVR, or use ONVIF/SDK tools to query the firmware version. Compare the installed version date against the April 2022 release.
    Affected if The firmware version date is earlier than April 2022 (e.g., March 2022 or older).
  3. Confirm ONVIF service is enabled
    Check the camera or NVR settings for ONVIF configuration. Use ONVIF device finder tools or probe port 80/8080 to verify the ONVIF service is actively running and accessible.
    Affected if ONVIF authentication is enabled and accessible on the network.

You are affected if you have any of the eight listed Dahua camera models with firmware dated before April 2022 and with ONVIF authentication enabled.

Upgrade available Upgrade to 2022-04 or later
Fixed in 2022-04
Interim mitigation

Implement replay protection in ONVIF authentication using nonces or timestamps, and enforce TLS encryption for all ONVIF communications to prevent packet capture.

Recommended fix Moderate confidence

Dahua IPC Firmware 2022-04 or later (specific model-appropriate version)

  1. 1. Identify the specific Dahua IPC model (Hdbw2431e S S2, Hdbw2831e S S2, Hdbw2230e S S2, Hdbw2831r Zs S2, Hdbw2831r Zas S2, Hdbw2531r Zs S2, Hdbw2531r Zas S2, or Hdbw2531e S S2) that needs remediation
  2. 2. Access the device web interface or use Dahua's configuration tool to check the current firmware version
  3. 3. Download the latest firmware from the official Dahua Security website (www.dahuasecurity.com) - ensure the firmware version is 2022-04 or later
  4. 4. Backup the device configuration if possible before upgrading
  5. 5. Upload and apply the firmware update following Dahua's standard firmware upgrade procedure
  6. 6. After the upgrade completes, verify the new firmware version is 2022-04 or later
  7. 7. Confirm that ONVIF authentication now includes protection against replay attacks
  8. 8. As an additional mitigation, ensure devices are not exposed to untrusted networks and consider using VPN or firewall rules to prevent MITM attacks on the local network
Caveat Firmware upgrades may reset configuration to defaults; backup configuration before upgrading and re-apply settings after upgrade
