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
Longse NVR (Network Video Recorder) model NVR3608PGE2W, as well as products based on this device, are transmitting user's login and password to a remote control service without using any encryption. This enables an on-path attacker to eavesdrop the credentials and subsequently obtain access to the video stream.  The credentials are being sent when a user decides to change his password in router's portal.

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

Longse NVR model NVR3608PGE2W transmits user login credentials in cleartext (unencrypted) when users change their password through the device's web portal. An on-path attacker can intercept these credentials and gain unauthorized access to the device and its video streams.

MitigationEnable HTTPS/TLS encryption for all web portal communications, or apply vendor firmware update if available. Until fixed, avoid changing passwords over untrusted networks and consider network segmentation as a compensating control.

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 the NVR device model
    Access the device web interface or check the physical device label for model number NVR3608PGE2W
    Affected if Device model is NVR3608PGE2W
  2. Verify if HTTPS is enabled for the web portal
    Check the device web interface settings under Network or Security settings for an SSL/TLS/HTTPS option, or attempt to access the login page using https:// instead of http://
    Affected if HTTPS is not available or not enforced for the web portal
  3. Capture network traffic during password change
    Use a network sniffer or proxy to observe traffic when changing the password through the web portal; check if the HTTP request body contains plaintext credentials
    Affected if Credentials are sent in cleartext HTTP POST data without encryption
  4. Check browser for secure connection indicator
    During password change, observe the browser address bar - verify no lock icon or secure connection indicator is present
    Affected if Connection shows as insecure or no padlock icon is displayed

The device is affected if it is a Longse NVR3608PGE2W model and the password change function transmits credentials over unencrypted HTTP rather than HTTPS.
