CVE-2025-20061 Overview
CVE-2025-20061 is a critical command injection vulnerability affecting mySCADA myPRO, an industrial control system (ICS) software platform. The vulnerability exists because mySCADA myPRO does not properly neutralize POST requests sent to a specific port with email information. This flaw could be exploited by an attacker to execute arbitrary commands on the affected system, potentially leading to complete system compromise.
Critical Impact
This vulnerability allows unauthenticated remote attackers to execute arbitrary commands on affected mySCADA myPRO systems, posing severe risks to industrial control environments and critical infrastructure.

Technical Details for CVE-2025-20061
Vulnerability Analysis
This vulnerability is classified as CWE-78 (Improper Neutralization of Special Elements used in an OS Command), commonly known as OS Command Injection. The flaw stems from insufficient input validation and sanitization of POST request data containing email information sent to a specific network port on the mySCADA myPRO system.
When processing incoming POST requests with email-related parameters, the application fails to properly neutralize special characters and command sequences. This allows an attacker to inject malicious OS commands that are subsequently executed with the privileges of the mySCADA myPRO application process. Given the network-accessible nature of this vulnerability, attackers can exploit it remotely without requiring prior authentication or user interaction.
Industrial control systems like mySCADA myPRO are particularly sensitive targets, as successful exploitation could allow attackers to manipulate SCADA processes, access sensitive operational data, or pivot to other systems within the industrial network.
Root Cause
The root cause of this vulnerability lies in improper input validation within the email handling functionality of mySCADA myPRO. The application fails to sanitize user-supplied input in POST requests before passing it to system-level command execution functions. This lack of proper neutralization allows specially crafted input containing shell metacharacters or command sequences to be interpreted and executed by the underlying operating system.
Attack Vector
The attack vector for CVE-2025-20061 is network-based, requiring no authentication or user interaction. An attacker can craft malicious POST requests containing command injection payloads within email-related parameters and send them to the vulnerable port exposed by mySCADA myPRO. Upon processing the malicious request, the injected commands execute on the target system with the privileges of the application process.
The vulnerability mechanism involves improper handling of POST request data containing email information. When this data reaches the command execution pathway without proper sanitization, shell metacharacters such as semicolons, pipes, or command substitution syntax can break out of the intended context and execute attacker-controlled commands. For detailed technical information, refer to the CISA ICS Advisory ICSA-25-023-01.
Detection Methods for CVE-2025-20061
Indicators of Compromise
- Unusual POST requests to the mySCADA myPRO email handling port containing shell metacharacters or command sequences
- Unexpected child processes spawned by the mySCADA myPRO application
- Anomalous network connections originating from the mySCADA myPRO server
- System logs showing command execution attempts with suspicious parameters
Detection Strategies
- Monitor network traffic for POST requests to the vulnerable mySCADA myPRO port containing potential command injection patterns
- Implement intrusion detection rules to identify shell metacharacters in email-related POST parameters
- Deploy endpoint detection solutions to monitor for unexpected process creation from the mySCADA myPRO application
- Review application and system logs for indicators of command execution attempts
Monitoring Recommendations
- Enable detailed logging for the mySCADA myPRO application and associated network services
- Configure SIEM rules to alert on suspicious POST request patterns targeting the affected port
- Monitor for unexpected outbound network connections from ICS/SCADA systems
- Implement network segmentation monitoring to detect lateral movement attempts
How to Mitigate CVE-2025-20061
Immediate Actions Required
- Review the CISA ICS Advisory ICSA-25-023-01 for vendor-specific patch information and remediation guidance
- Implement network segmentation to isolate mySCADA myPRO systems from untrusted networks
- Restrict network access to the affected port using firewall rules
- Monitor systems for indicators of compromise while awaiting patch deployment
Patch Information
Organizations should consult the CISA ICS Advisory ICSA-25-023-01 for the latest patch information and vendor recommendations. Apply security updates as soon as they become available from mySCADA.
Workarounds
- Implement strict network access controls to limit connectivity to mySCADA myPRO systems to trusted hosts only
- Deploy a web application firewall (WAF) or reverse proxy with input validation rules to filter malicious POST requests
- Disable or restrict access to the vulnerable email functionality if not required for operations
- Ensure mySCADA myPRO systems are not directly accessible from the internet or untrusted networks
