CVE-2017-6342
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 · uneditedAn issue was discovered on Dahua DHI-HCVR7216A-S3 devices with NVR Firmware 3.210.0001.10 2016-06-06, Camera Firmware 2.400.0000.28.R 2016-03-29, and SmartPSS Software 1.16.1 2017-01-19. When SmartPSS Software is launched, while on the login screen, the software in the background automatically logs in as admin. This allows sniffing sensitive information identified in CVE-2017-6341 without prior knowledge of the password. This is a different vulnerability than CVE-2013-6117.
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 confidenceDahua SmartPSS software contains an authentication bypass vulnerability where it automatically logs in as admin in the background while the user sees the login screen, allowing unauthorized access to sensitive information without knowing the password. This affects NVR firmware 3.210.0001.10, camera firmware 2.400.0000.28.R, and SmartPSS 1.16.1.

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 checksWork through these to decide whether this CVE applies to you.
-
Check SmartPSS software versionOpen SmartPSS, navigate to Help > About, or right-click the application icon and select Properties to view the version informationAffected if Version is 1.16.1
-
Check NVR firmware versionAccess the NVR web interface or login to the NVR locally, navigate to Settings > System > Version or Info to view the firmware versionAffected if Firmware version is 3.210.0001.10
-
Check IP camera firmware versionAccess the camera web interface, navigate to Setup > System > Version, or use the Dahua Config Tool to scan and display firmware versions of connected camerasAffected if Camera firmware version is 2.400.0000.28.R
-
Verify if remote access is enabledCheck the network settings on the NVR or camera web interface for remote access features such as P2P, cloud connection, or port forwarding configurations that expose the device to external networksAffected if Remote/network access is enabled and the device is accessible from untrusted networks
-
Review access logs for anomalous admin sessionsCheck the NVR or SmartPSS event logs, user logs, or access logs for sessions logged as admin that occurred during times when no legitimate administrator was expected to loginAffected if Admin sessions appear in logs without corresponding legitimate login events
You are affected if any of your Dahua cameras, NVRs, or SmartPSS installations match the exact version numbers 2.400.0000.28.R, 3.210.0001.10, or 1.16.1 respectively, and are exposed to network access.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate SmartPSS software, NVR firmware, and camera firmware to patched versions. Until updates are available, network segment the affected devices and restrict access to trusted users only.
