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) version 1.6 contains a default credentials vulnerability that allows unauthorized attackers to gain administrative access. Attackers can exploit the weak default administrative credentials to obtain full control of the home automation system.

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

The Ksenia Security lares home automation system version 1.6 ships with weak default administrative credentials that cannot be changed by users. Attackers with network access to the device can authenticate using these hardcoded credentials to gain full administrative control of the system.

MitigationImmediately change the default administrative credentials to strong, unique passwords and restrict network access to the management interface. If credentials cannot be changed, isolate the device on a restricted network segment.

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 device and firmware version
    Access the Lares web interface or check the device system information page to determine the exact firmware version. Compare against the affected version 1.6.
    Affected if The device is a Ksenia Security Lares system running firmware version 1.6
  2. Verify credential change capability
    Navigate to the administrative settings panel in the Lares web interface and attempt to change the default administrative password. Observe whether the system allows password modification or returns an error indicating credentials cannot be changed.
    Affected if The system does not allow changing the default administrative credentials or the change does not persist across reboots
  3. Check if default credentials are active
    Log out of the current administrative session and attempt to authenticate using the known default administrative username and password for the Lares 1.6 system.
    Affected if The default credentials successfully grant administrative access to the system
  4. Assess network exposure of management interface
    Determine if the Lares management web interface (typically ports 80/443 or configured HTTP/HTTPS port) is accessible from untrusted networks, the internet, or network segments without proper access controls.
    Affected if The administrative interface is reachable from networks outside the trusted local network without VPN or firewall protections

A user is affected if they operate a Ksenia Security Lares system on firmware version 1.6 with default credentials that remain active and the management interface is network-accessible to potential attackers.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Immediately change the default administrative credentials to strong, unique passwords and restrict network access to the management interface. If credentials cannot be changed, isolate the device on a restricted network segment.

Recommended fix Moderate confidence

Contact vendor for latest firmware version - no fixed version specified in available sources

  1. Change the default administrative credentials immediately upon first login to the Lares system
  2. Access the web interface or admin panel of the Lares home automation system
  3. Navigate to the user management or administrator settings section
  4. Locate the default admin account and change its password to a strong, unique password
  5. If available, create a new administrator account and disable or delete the default admin account
  6. Verify the new credentials work correctly before logging out
  7. Contact Ksenia Security directly to inquire about firmware updates that address this vulnerability
  8. Check Ksenia Security's official website or support channels for any available security patches or firmware updates
