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
The Eurolab ELTS100_UBX device (firmware version ELTS100v1.UBX) is vulnerable to Broken Access Control due to missing authentication on critical administrative endpoints. Attackers can directly access and modify sensitive system and network configurations, upload firmware, and execute unauthorized actions without any form of authentication. This vulnerability allows remote attackers to fully compromise the device, control its functionality, and disrupt its operation.

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 Eurolab ELTS100_UBX device (firmware ELTS100v1.UBX) contains a Broken Access Control vulnerability where critical administrative endpoints lack authentication. This allows unauthenticated remote attackers to access and modify system/network configurations, upload arbitrary firmware, and execute administrative actions, resulting in full device compromise.

MitigationImplement strong authentication and authorization controls on all administrative endpoints, enforce proper session management, validate firmware authenticity before upload, and restrict network access to trusted sources.

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 model
    Check device label, web management interface, SNMP sysDescr, or network scan for device identification
    Affected if Device is identified as Eurolab ELTS100 or ELTS100_UBX
  2. Determine the firmware version
    Access the device web interface, check system information page, or query SNMP OID for firmware version
    Affected if Firmware version is exactly elts100v1.ubx (exact version match)
  3. Test administrative endpoint access without credentials
    Attempt to access common admin paths such as /admin, /settings, /config, /firmware, or /system via HTTP/HTTPS without providing any username or password
    Affected if Administrative pages or APIs respond successfully without requiring any authentication credentials

You are affected if you have an Eurolab ELTS100 device running firmware version elts100v1.ubx and administrative interfaces are accessible without any authentication.
