ST Engineering iDirect iQ-Series Terminals

View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to gain unauthorized access to device information or cause a denial-of-service condition. The following versions of ST Engineering iDirect iQ-Series Terminals are affected: Evolution iQ‑Series terminals <=4.5.2.1 (CVE-2026-38059, CVE-2026-38057) 3315‑Series terminals <=4.5.2.1 (CVE-2026-38059, CVE-2026-38057) 9‑Series terminals <=4.5.2.1 (CVE-2026-38059, CVE-2026-38057) CVSS Vendor Equipment Vulnerabilities v3 8.1 ST Engineering iDirect ST Engineering iDirect iQ-Series Terminals Missing Authentication for Critical Function, Cross-Site Request Forgery (CSRF) Background Critical Infrastructure Sectors: Communications, Defense Industrial Base, Energy, Government Services and Facilities, Transportation Systems Countries/Areas Deployed: Worldwide Company Headquarters Location: United States Vulnerabilities Expand All + CVE-2026-38059 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.

The /api/reboot endpoint accepts POST requests authenticated solely by a session cookie that lacks the SameSite attribute. A remote attacker can host a malicious web page that, when visited by an authenticated administrator, automatically submits a cross-site POST request causing an immediate device reboot and satellite link loss. Repeated attacks can sustain a denial-of-service condition.

Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as
