Urgent Action Required: Mitigating CVE-2025-13913 in Inductive Automation Ignition

The Cybersecurity and Infrastructure Security Agency (CISA) recently released an advisory regarding a significant security vulnerability in Inductive Automation Ignition Software. As this platform is a cornerstone for many industrial control systems (ICS) and operational technology (OT) environments, understanding and remediating this issue is a high priority for defenders worldwide.

Introduction

At its core, CVE-2025-13913 is a deserialization of untrusted data vulnerability. While this sounds highly technical, the implication is straightforward: an attacker can trick the software into running malicious code.

In this specific scenario, if an authenticated user with sufficient privileges imports a specially crafted file—perhaps believing it to be a legitimate project backup or configuration—the attacker can execute arbitrary code. This code runs with the permissions of the Ignition service account, which often has elevated access to the underlying operating system. For defenders, this represents a critical pivot point where an application-level compromise can turn into a full host takeover.

Technical Analysis

The vulnerability specifically affects versions of Ignition prior to 8.3.0.

• Vulnerability ID: CVE-2025-13913
• Affected Products: Inductive Automation Ignition Software < 8.3.0
• Vendor: Inductive Automation
• Sector: Information Technology (though heavily used in Critical Infrastructure/OT)
• CVSS Score (v3): 6.3 (Medium)

The flaw arises because the application does not properly validate data during the "deserialization" process (reading data and converting it back into an object). A malicious user, or a compromised privileged account, can weaponize an imported file. Once imported, the payload executes, potentially allowing an attacker to:

1. Move laterally within the OT network.
2. Disrupt industrial processes.
3. Deploy ransomware or other malware.

While a CVSS of 6.3 is "Medium," the potential impact on ICS environments makes this a high-priority patch for security operations teams.

Defensive Monitoring

To assist your security team in identifying vulnerable instances and verifying patch compliance, we have developed the following detection scripts and queries.

PowerShell: Inventory Ignition Versions

This script can be run on Windows Servers where Ignition is suspected to be installed. It checks the registry and common installation paths to identify the software version.

<#
.SYNOPSIS
    Checks for Inductive Automation Ignition installation and version.
.DESCRIPTION
    This script queries the registry and file system to find Ignition installations
    and determine if they are vulnerable to CVE-2025-13913 (< 8.3.0).
#>

$VulnerableThreshold = [version]"8.3.0"
$VulnerableHosts = @()

# Check Registry for Uninstall Information
$installedSoftware = Get-ItemProperty "HKLM:\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"
$installedSoftware += Get-ItemProperty "HKLM:\\Software\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\*"

foreach ($app in $installedSoftware) {
    if ($app.DisplayName -like "*Ignition*") {
        $installPath = $app.InstallLocation
        if (-not $installPath) { continue }
        
        # Attempt to find gateway launch config or similar version file
        $versionFile = Join-Path -Path $installPath -ChildPath "lib\\core\\gateway\\gateway-8.x.x.jar"
        
        # Check common specific file or use registry version if available
        $currentVersion = $app.DisplayVersion
        
        if ($currentVersion) {
            try {
                $verObj = [version]$currentVersion
                if ($verObj -lt $VulnerableThreshold) {
                    Write-Host "[ALERT] Vulnerable Ignition found: $($app.DisplayName) Version: $currentVersion at $installPath"
                    $VulnerableHosts += [PSCustomObject]@{
                        ComputerName = $env:COMPUTERNAME
                        Product = $app.DisplayName
                        Version = $currentVersion
                        Path = $installPath
                        Status = "Vulnerable"
                    }
                }
                else {
                    Write-Host "[OK] Ignition found: $($app.DisplayName) Version: $currentVersion (Patched)"
                }
            }
            catch {
                Write-Host "[WARN] Could not parse version for $($app.DisplayName)"
            }
        }
    }
}

if ($VulnerableHosts.Count -eq 0) {
    Write-Host "No vulnerable Ignition installations detected via Registry."
}

KQL Query for Microsoft Sentinel

If you have installed Ignition on Windows servers and are forwarding Security events or Process creation events to Sentinel, use this query to identify hosts running the Ignition gateway process (gwcmd.exe or wrapper.exe). You can cross-reference these results with your asset inventory to verify patch status.

// Hunt for Ignition Gateway Processes
DeviceProcessEvents
| where FileName in~ ("wrapper.exe", "gwcmd.exe", "java.exe") 
// Note: Java.exe is generic, so we filter by folder path if possible
| where FolderPath contains @"Ignition" 
| extend IgnitionPath = FolderPath
| summarize arg_max(Timestamp, *) by DeviceId, DeviceName
| project Timestamp, DeviceName, AccountName, IgnitionPath, InitiatingProcessFileName
| extend timestamp = format_datetime(Timestamp, 'yyyy-MM-dd HH:mm:ss')
| sort by Timestamp desc

Remediation

Protecting your organization against CVE-2025-13913 requires immediate action. Security teams should follow these steps:

1. Patch Immediately: The definitive remediation is to upgrade Inductive Automation Ignition Software to version 8.3.0 or later. Download the latest update directly from the Inductive Automation customer portal.

2. Verify the Update: After patching, run the PowerShell script provided above or manually check the "About" section in the Ignition Gateway web interface to confirm the version is 8.3.0+.

3. Review User Privileges: This vulnerability requires an authenticated, privileged user to import a file. Ensure that the number of users with "Project Import" or administrative privileges is limited to only those who strictly need it.

4. Audit Recent Imports: If you suspect suspicious activity prior to patching, review Ignition Gateway logs for "Project Import" or "Gateway Restore" events initiated by unexpected users.

5. Network Segmentation: Ensure that Ignition servers are isolated from the general IT network and the internet, minimizing the attack surface if a user account is compromised via other means (like phishing).
