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
A vulnerability exists in SenseLive X3050’s web management interface due to its reliance on unencrypted HTTP for all administrative communication. Because management traffic, including authentication attempts and configuration data, is transmitted in cleartext, an attacker with access to the same network segment could intercept or observe sensitive operational information.

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 · moderate confidence

The SenseLive X3050 web management interface transmits all administrative traffic, including authentication credentials and configuration data, over unencrypted HTTP. An attacker with network proximity can intercept this cleartext traffic to capture sensitive operational information or hijack sessions.

MitigationEnable TLS/HTTPS encryption on the SenseLive X3050 web management interface and redirect all HTTP traffic to HTTPS to protect administrative communications from eavesdropping.

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 SenseLive device model
    Access the device web management interface or check the device label/dashboard to confirm the exact model number (X3050 or X3500)
    Affected if The device is a SenseLive X3050 or X3500 model
  2. Check the installed firmware version
    Navigate to the web management interface firmware or system information page, or use the command line interface to retrieve the firmware version
    Affected if The firmware version is 1.523
  3. Verify if HTTP is enabled for the web interface
    Attempt to access the device web management interface using http:// (port 80) rather than https://
    Affected if The web interface is accessible over HTTP (port 80) without redirection to HTTPS
  4. Confirm HTTPS is not enforced or available
    Check the web interface security settings or try accessing with https:// to see if HTTPS is configured and enforced
    Affected if HTTPS is not enabled or not enforced for administrative access
  5. Check if sensitive operations transmit in cleartext
    Use a network capture tool on the same network segment while logging into the web interface or making configuration changes
    Affected if Authentication credentials or configuration data are transmitted in cleartext over HTTP

You are affected if you have a SenseLive X3500 device running firmware version 1.523 and the web management interface is accessible over unencrypted HTTP.
