## Overview

The iDirect iQ200 exposes the /api/identity and /api/ REST API endpoints without authentication. An unauthenticated attacker with network access can retrieve sensitive device information including the serial number, Device ID (DID), Terminal Private Key identifier (TPK), MAC address, and exact firmware version. The DID and TPK are used for satellite network authentication in the iDirect platform, potentially enabling terminal impersonation and network reconnaissance.

## Affected

- `evolution_iq_series_terminals <= 4.5.2.1`
- `3315-series_terminals <= 4.5.2.1`
- `9-series_terminals <= 4.5.2.1`

## Remediation

ST Engineering iDirect has fixed the vulnerabilities and recommend users update the software to version 4.5.3.0 or newer.




Registered users are able to download patches from the iDirect Support Portal:  https://support.idirect.net https://support.idirect.net/ 

  *  Restrict management interfaces to trusted networks (e.g., VPN, ACLs).
  *  Avoid exposing administrative APIs to the public internet.
  *  Enforce strong authentication practices.
  *  Monitor for anomalous API activity and unexpected device reboots.
