CVE-2025-20014 Overview
CVE-2025-20014 is a critical command injection vulnerability (CWE-78) affecting mySCADA myPRO, a SCADA (Supervisory Control and Data Acquisition) management system. The vulnerability exists due to improper neutralization of POST requests sent to a specific port containing version information. This flaw allows unauthenticated remote attackers to execute arbitrary commands on vulnerable systems, potentially leading to complete system compromise.
mySCADA myPRO is an industrial control system (ICS) software used in critical infrastructure environments for monitoring and managing industrial processes. The severity of this vulnerability is significantly amplified by its deployment in operational technology (OT) environments where unauthorized access could impact physical processes.
Critical Impact
Remote attackers can execute arbitrary commands on affected mySCADA myPRO systems without authentication, potentially compromising critical infrastructure operations and gaining full control of industrial processes.
Affected Products
- mySCADA myPRO (all versions prior to patched release)
- Industrial control systems running vulnerable myPRO installations
- SCADA environments utilizing mySCADA software

Technical Details for CVE-2025-20014
Vulnerability Analysis
This vulnerability is classified as OS Command Injection (CWE-78), one of the most severe classes of web application vulnerabilities. The flaw exists in the POST request handling mechanism of mySCADA myPRO, specifically in how the application processes version information parameters sent to a designated network port.
When processing incoming POST requests, the application fails to properly sanitize or validate user-supplied input before incorporating it into operating system commands. This lack of input neutralization creates an injection point where attackers can append arbitrary shell commands that the system will execute with the privileges of the application process.
The network-accessible nature of this vulnerability is particularly concerning in ICS/SCADA environments, where such systems often operate on flat networks with limited segmentation. An attacker who gains network access—whether through compromised credentials, VPN access, or lateral movement—could exploit this vulnerability to execute commands on systems controlling critical industrial processes.
Root Cause
The root cause of CVE-2025-20014 is insufficient input validation and improper neutralization of special characters in POST request parameters. The application accepts version information through HTTP POST requests but fails to implement proper input sanitization before using this data in command execution contexts.
Specifically, the application does not adequately filter or escape shell metacharacters such as semicolons (;), pipes (|), backticks (`), dollar signs with parentheses ($()), and other command separators that could allow command chaining or substitution. This allows malicious input to break out of the intended command context and execute attacker-controlled commands.
Attack Vector
The attack is network-based and requires no authentication or user interaction. An attacker can exploit this vulnerability by:
- Identifying a network-accessible mySCADA myPRO instance
- Crafting a malicious POST request containing version information parameters
- Injecting shell commands within the version parameter using command separators
- Sending the request to the vulnerable port
- Achieving arbitrary command execution on the target system
The vulnerability can be exploited remotely by any attacker with network access to the vulnerable service. Given the attack does not require authentication, systems exposed to the internet or accessible from compromised internal networks are at immediate risk.
For detailed technical information about the exploitation mechanism, refer to the CISA ICS Advisory ICSA-25-023-01.
Detection Methods for CVE-2025-20014
Indicators of Compromise
- Unusual POST requests to mySCADA myPRO services containing shell metacharacters (;, |, $(), backticks)
- Unexpected child processes spawned by the myPRO application process
- Anomalous network connections originating from the myPRO server to external hosts
- Evidence of reconnaissance commands (e.g., whoami, id, uname) in process logs
- New user accounts or modified credentials on systems running myPRO
Detection Strategies
- Deploy network intrusion detection rules to identify POST requests with command injection patterns targeting myPRO endpoints
- Monitor application and system logs for command execution attempts containing shell metacharacters
- Implement behavioral analysis to detect unusual process trees originating from SCADA applications
- Configure SIEM alerts for authentication anomalies and privilege escalation attempts on ICS systems
Monitoring Recommendations
- Enable verbose logging on all mySCADA myPRO installations and forward logs to a centralized SIEM
- Implement network traffic analysis (NTA) solutions to baseline normal OT network behavior and alert on deviations
- Monitor for unexpected outbound connections from SCADA systems, particularly to internet-facing addresses
- Establish real-time alerting for any command execution or shell activity on dedicated ICS hosts
How to Mitigate CVE-2025-20014
Immediate Actions Required
- Review the CISA ICS Advisory ICSA-25-023-01 for vendor-specific remediation guidance
- Restrict network access to mySCADA myPRO systems using firewalls and network segmentation
- Implement strict access controls limiting connectivity to authorized management stations only
- Monitor vulnerable systems for exploitation attempts while preparing to apply patches
- Conduct an inventory of all mySCADA myPRO deployments in your environment
Patch Information
Organizations should consult the official CISA ICS Advisory ICSA-25-023-01 for specific patch information and remediation guidance from mySCADA. Apply vendor-provided security updates as soon as they become available, following change management procedures appropriate for OT environments.
Workarounds
- Isolate mySCADA myPRO systems on dedicated network segments with strict firewall rules preventing unauthorized access
- Implement application-layer firewalls or web application firewalls (WAF) to filter malicious POST requests
- Deploy virtual patching through IDS/IPS signatures to block known exploitation patterns
- Disable or restrict access to the vulnerable port if not required for operational purposes
- Implement network monitoring to detect and alert on exploitation attempts
# Network segmentation example - restrict access to myPRO service
# Allow only authorized management workstations
iptables -A INPUT -p tcp --dport <mypro_port> -s <authorized_mgmt_subnet> -j ACCEPT
iptables -A INPUT -p tcp --dport <mypro_port> -j DROP
