CVE-2023-32348
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 · uneditedTeltonika’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 confidenceTeltonika 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Teltonika RMS installationLocate 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
-
Determine the installed RMS versionAccess 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
-
Compare version against affected rangeCompare 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
-
Check if VPN hub feature is in useExamine 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.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.10.0
Upgrade Teltonika Remote Management System to version 4.10.0 or later, which contains the fix for the improper VPN access controls.
4.10.0
- Upgrade Teltonika Remote Management System to version 4.10.0 or later
- After upgrading, verify the OpenVPN configuration does not allow unauthorized routing through the VPN server
- Confirm that the VPN hub feature no longer permits cross-device communication without proper authentication
