CVE-2026-38059

ST Engineering iDirect iQ-Series Terminals Missing authentication for critical function

State: Published
Severity: 8.7 High
Published: Jul 10, 2026
Updated: Sep 11, 2026
Reserved: Apr 6, 2026

Description

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.
