CVE-2023-29169
📋 TL;DR
This vulnerability allows authenticated users to inject arbitrary operating system commands in mySCADA myPRO versions 8.26.0 and prior. Attackers with valid credentials can execute commands with the privileges of the myPRO application, potentially compromising the entire system. Industrial control systems using vulnerable mySCADA installations are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands with application privileges, potentially leading to ransomware deployment, data theft, or disruption of industrial processes.
Likely Case
Authenticated attackers gaining shell access to the underlying operating system, enabling lateral movement, data exfiltration, or installation of persistent backdoors.
If Mitigated
Limited impact if proper network segmentation, least privilege access, and command validation are implemented, restricting the blast radius.
🎯 Exploit Status
Exploitation requires authenticated access but command injection is straightforward once authenticated; no public exploit code is known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.27.0 or later
Vendor Advisory: https://www.cisa.gov/news-events/ics-advisories/icsa-23-096-06
Restart Required: Yes
Instructions:
1. Download mySCADA myPRO version 8.27.0 or later from the vendor. 2. Backup current configuration and data. 3. Install the updated version following vendor instructions. 4. Restart the myPRO service or system as required.
🔧 Temporary Workarounds
Restrict Network Access
allLimit access to myPRO interface to trusted IP addresses only using firewall rules.
Implement Least Privilege
allReduce the number of authenticated users and ensure they have minimal necessary permissions.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate myPRO systems from critical networks.
- Deploy application-level firewalls or WAFs with command injection detection rules.
🔍 How to Verify
Check if Vulnerable:
Check the myPRO version in the application interface or configuration files; versions 8.26.0 or earlier are vulnerable.Check Version:
Check the application GUI or configuration files for version information; no universal CLI command exists.Verify Fix Applied:
Verify the installed version is 8.27.0 or later and test command injection attempts to ensure they are blocked.📡 Detection & Monitoring
Log Indicators:
