CVE-2023-50219
📋 TL;DR
This vulnerability in Inductive Automation Ignition allows authenticated remote attackers to execute arbitrary code with SYSTEM privileges by exploiting insecure deserialization in the RunQuery class. It affects Ignition installations where attackers can authenticate to the system. The CVSS 8.8 score reflects the high impact of remote code execution with authentication requirements.

📦 What is this software?
Ignition by Inductiveautomation
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with SYSTEM privileges, allowing attackers to install malware, exfiltrate data, pivot to other systems, and maintain persistent access.
Likely Case
Unauthorized code execution leading to data theft, system manipulation, or deployment of ransomware within the Ignition environment.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring in place to detect exploitation attempts.
🎯 Exploit Status
Authentication required but exploit likely straightforward once authenticated. ZDI advisory suggests weaponization is probable.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://security.inductiveautomation.com/?tcuUid=fc4c4515-046d-4365-b688-693337449c5b
Restart Required: Yes
Instructions:
1. Review vendor advisory for affected versions
2. Download and apply latest Ignition patch from official vendor site
3. Restart Ignition services
4. Verify patch application
🔧 Temporary Workarounds
Network Segmentation
allRestrict access to Ignition systems to only trusted networks and users
Authentication Hardening
allImplement strong authentication policies, multi-factor authentication, and account lockouts
🧯 If You Can't Patch
- Implement strict network access controls to limit who can reach Ignition systems
- Enable detailed logging and monitoring for suspicious RunQuery activity
🔍 How to Verify
Check if Vulnerable:
Check Ignition version against vendor advisory. Review if RunQuery functionality is exposed to authenticated users.Check Version:
Check Ignition Gateway Web UI or configuration files for version informationVerify Fix Applied:
Verify Ignition version is updated to patched version specified in vendor advisory. Test RunQuery functionality with malformed inputs.📡 Detection & Monitoring
Log Indicators:
- Unusual RunQuery activity patterns
- Multiple failed authentication attempts followed by successful RunQuery execution
- Unexpected process creation from Ignition services
Network Indicators:
- Suspicious traffic to Ignition ports from unexpected sources
- Anomalous serialized data patterns in network traffic
SIEM Query:
source="ignition" AND (event="RunQuery" OR process="java") AND (user="*" OR command="*serial*" OR data="*serial*")
