CVE-2026-38056

ST Engineering iDirect iQ-Series Terminals Missing Authorization

Published Sep 11, 2026 CVSS 4.0 · 9.4 Critical EPSS < 1% KEV · Not listed
Description
A local privilege escalation vulnerability exists in the iDirect iQ200 VSAT terminal running firmware 23.0.1.0. The iQ200 is a rackmount satellite modem deployed across oil and gas, maritime, defense, and remote infrastructure as the primary, and often sole communications link for offshore rigs, vessels, and remote sites. Important context: the device ships from the factory with a pre-configured low-privilege local user account. This account is intended for field technicians who need shell access for maintenance and diagnostics but should not have full administrative control over the device. This built-in account provides the initial access required to exploit this vulnerability. No additional credentials need to be obtained or brute-forced.

Remediation

Vendor Solution

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.
