CVE-2023-38124: Inductive Automation Ignition Gateway exposed dangerous function RCE
Inductiveautomation · Ignition
Inductive Automation Ignition Gateway exposes a dangerous function in its OPC UA Quick Client task scheduling component, allowing an authenticated remote attacker to execute arbitrary code. The flaw is a CWE-749 exposed dangerous function issue in the Ignition Gateway server. It matters because successful exploitation yields code execution as SYSTEM on an industrial automation platform.
Description
Inductive Automation Ignition OPC UA Quick Client Task Scheduling Exposed Dangerous Function Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Inductive Automation Ignition. Authentication is required to exploit this vulnerability. The specific flaw exists within the Ignition Gateway server. The issue results from the exposure of a dangerous function. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-20541.
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Automated analysis
high priorityCVSS 8.8 with network reachability and SYSTEM-level code execution, plus very high EPSS, though authentication is required and no KEV listing exists.
What it is
Inductive Automation Ignition Gateway exposes a dangerous function in its OPC UA Quick Client task scheduling component, allowing an authenticated remote attacker to execute arbitrary code. The flaw is a CWE-749 exposed dangerous function issue in the Ignition Gateway server. It matters because successful exploitation yields code execution as SYSTEM on an industrial automation platform.
Impact
An attacker gains arbitrary code execution in the context of SYSTEM on the Ignition Gateway server. This can lead to full compromise of the gateway and potentially connected industrial control systems.
Attack surface
Reachable over the network via the Ignition Gateway server (AV:N, AC:L). Authentication is required (PR:L) and no user interaction is needed (UI:N).
Exploitation
Not listed in CISA KEV and no ransomware usage documented. EPSS is 0.59609 (99th percentile), indicating a high predicted likelihood of exploitation, though no public exploit is confirmed in the record.
What to do
- Apply the vendor patch or upgrade to a fixed Ignition version as referenced in the vendor advisory.
- Restrict network access to the Ignition Gateway and OPC UA interfaces to trusted hosts only.
- Enforce least privilege for Ignition accounts and avoid granting unnecessary task scheduling permissions.
- Monitor and audit task scheduling configurations for unauthorized changes.
- Segment industrial networks to limit lateral movement from a compromised gateway.
Detection
- Monitor Ignition Gateway logs for unexpected task scheduling creation or modification events.
- Alert on processes spawning from the Ignition Gateway service, especially those running as SYSTEM.
- Detect anomalous network connections to the OPC UA Quick Client or task scheduling endpoints.
- Review authentication logs for unusual or off-hours access to Ignition administrative functions.
