CVE-2026-38059 PUBLISHED

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

Assigner: icscert
Reserved: 06.04.2026 Published: 10.07.2026 Updated: 10.07.2026

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.
