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
Waybox Enel TCF Agent service could be used to get administrator’s privileges over the Waybox 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 · low confidence

The Waybox Enel TCF Agent service contains a vulnerability that allows an authenticated attacker to escalate privileges to administrator level on the Waybox system. The specific technical details of the exploitation mechanism are not publicly documented in available sources.

MitigationApply any available vendor patches for the Waybox Enel TCF Agent. If no patch exists, restrict access to the TCF Agent service to trusted administrative personnel only and monitor for unauthorized privilege escalation attempts.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Waybox Enel TCF Agent service
    Check if the Waybox Enel TCF Agent service is running on the system. Look for processes named 'tcf-agent', 'waybox-tcf', or similar in the process list. On Linux check: ps aux | grep -i tcf. On embedded devices, check /proc/ for running processes.
    Affected if The TCF Agent service is present and running on the system
  2. Check firmware version
    Retrieve the installed firmware version of the Enelx Waybox Pro device. This is typically found in the device web interface under 'Settings' > 'System' > 'Firmware Version', or via CLI command such as 'cat /etc/version', 'fw_printenv', or checking /proc/cmdline. Compare the version string to the affected range: < 2.1.1.0_jb3vu096a.
    Affected if The installed firmware version is less than 2.1.1.0_jb3vu096a
  3. Verify TCF Agent authentication configuration
    Examine the TCF Agent configuration files for authentication settings. Look for configuration files in /etc/tcf/, /opt/waybox/config/, or similar paths. Check if authentication is enforced for TCF Agent connections and verify that default or weak credentials are not in use.
    Affected if TCF Agent authentication is disabled, using default credentials, or improperly configured allowing unauthorized access
  4. Review TCF Agent access logs
    Inspect TCF Agent service logs for privilege escalation indicators. Look for logs in /var/log/tcf/, /var/log/waybox/, or system logs (syslog, journalctl). Search for events indicating administrator role assignment, privilege changes, or unusual authenticated actions.
    Affected if Logs show unauthorized administrator role assignments or privilege escalation events from non-admin accounts

A system is affected if it runs Enelx Waybox Pro firmware versions below 2.1.1.0_jb3vu096a with the TCF Agent service enabled and accessible to authenticated users.

Upgrade available Upgrade to 2.1.1.0_jb3vu096a or later
Fixed in 2.1.1.0_jb3vu096a
Interim mitigation

Apply any available vendor patches for the Waybox Enel TCF Agent. If no patch exists, restrict access to the TCF Agent service to trusted administrative personnel only and monitor for unauthorized privilege escalation attempts.

Recommended fix Moderate confidence

Waybox Pro Firmware 2.1.1.0_jb3vu096a

  1. 1. Identify the current firmware version of the Waybox Pro device
  2. 2. Access the Waybox Pro administrative interface or use the firmware update mechanism
  3. 3. Download the Waybox Pro Firmware version 2.1.1.0_jb3vu096a or later from the official Enel X support site (support-emobility.enelx.com)
  4. 4. Apply the firmware update following the manufacturer's documented upgrade procedure
  5. 5. Verify the upgrade was successful by confirming the new firmware version
  6. 6. Validate that the TCF Agent service now properly enforces access controls
