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
Teltonika’s Remote Management System versions prior to 4.10.0 contain a virtual private network (VPN) hub feature for cross-device communication that uses OpenVPN. It connects new devices in a manner that allows the new device to communicate with all Teltonika devices connected to the VPN. The OpenVPN server also allows users to route through it. An attacker could route a connection to a remote server through the OpenVPN server, enabling them to scan and access data from other Teltonika devices connected to the VPN.

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

Teltonika RMS versions before 4.10.0 have a VPN hub using OpenVPN that improperly allows any newly connected device to communicate with all other Teltonika devices on the VPN and to route traffic through the VPN server. This enables attackers to perform lateral movement, scan internal network resources, and access data from other VPN-connected devices.

MitigationUpgrade Teltonika Remote Management System to version 4.10.0 or later, which contains the fix for the improper VPN access controls.

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 Teltonika RMS installation
    Locate the Teltonika Remote Management System server or instance in your environment. Check for the RMS web interface, database, or associated services.
    Affected if Teltonika RMS is deployed in the environment and is accessible
  2. Determine the installed RMS version
    Access the RMS admin interface or check system files to find the current version number. Look in the about page, system info, or configuration files.
    Affected if The installed version is unknown or cannot be verified as 4.10.0 or later
  3. Compare version against affected range
    Compare your identified version to the affected range: versions before 4.10.0 are vulnerable, 4.10.0 and later are not.
    Affected if The installed version is below 4.10.0
  4. Check if VPN hub feature is in use
    Examine RMS configuration or settings to determine if the VPN hub functionality with OpenVPN is enabled and actively used.
    Affected if VPN hub with OpenVPN is enabled and devices are connected to it

You are affected if Teltonika RMS version is below 4.10.0 AND the VPN hub with OpenVPN feature is enabled in your deployment.

Upgrade available Upgrade to 4.10.0 or later
Fixed in 4.10.0
Interim mitigation

Upgrade Teltonika Remote Management System to version 4.10.0 or later, which contains the fix for the improper VPN access controls.

Recommended fix Moderate confidence

4.10.0

  1. Upgrade Teltonika Remote Management System to version 4.10.0 or later
  2. After upgrading, verify the OpenVPN configuration does not allow unauthorized routing through the VPN server
  3. Confirm that the VPN hub feature no longer permits cross-device communication without proper authentication
