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
Ksenia Security lares (legacy model) Home Automation version 1.6 contains a critical security flaw that exposes the alarm system PIN in the 'basisInfo' XML file after authentication. Attackers can retrieve the PIN from the server response to bypass security measures and disable the alarm system without additional authentication.

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

Ksenia Security lares (legacy model) Home Automation version 1.6 exposes the alarm system PIN in cleartext within the 'basisInfo' XML file after authentication. An authenticated attacker can retrieve this PIN from the server response to bypass security controls and disable the alarm system without additional verification.

MitigationUpdate to a patched version if available, or implement additional authorization controls to prevent PIN exposure in the basisInfo endpoint and enforce multi-factor authentication for critical alarm operations.

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. Confirm Ksenia Security lares product is deployed
    Identify the installed security system product name and confirm it is the Ksenia Security lares Home Automation platform
    Affected if The product is Ksenia Security lares Home Automation
  2. Verify firmware version is 1.6
    Access the device administrative interface or system information page and locate the firmware version field; compare against '1.6'
    Affected if Firmware version equals 1.6 exactly
  3. Check XML response for PIN exposure
    Log into the web interface with valid user credentials, navigate to any page or API endpoint that returns the 'basisInfo' XML structure, and inspect the response body for a PIN or passcode field
    Affected if The XML response contains a plaintext PIN in the basisInfo section
  4. Verify authentication is required
    Attempt to access the basisInfo XML endpoint without providing credentials; confirm whether the endpoint returns the PIN only after successful authentication
    Affected if The PIN is returned in the response after valid authentication (meaning any authenticated user can retrieve it)

You are affected if the system runs Ksenia Security lares firmware version 1.6 and the basisInfo XML response after authentication contains a plaintext alarm system PIN that can be retrieved by any authenticated user.
