CVE-2024-47407 Overview
CVE-2024-47407 is a critical OS command injection vulnerability affecting mySCADA myPRO Manager, an industrial control system (ICS) management platform. A parameter within a command does not properly validate input, which could be exploited by an unauthenticated remote attacker to inject arbitrary operating system commands. This vulnerability poses a severe risk to industrial environments where myPRO Manager is deployed for SCADA system management.
Critical Impact
Unauthenticated remote attackers can execute arbitrary operating system commands on affected myPRO Manager installations, potentially leading to complete system compromise of industrial control infrastructure.

Technical Details for CVE-2024-47407
Vulnerability Analysis
This vulnerability is classified under CWE-78 (Improper Neutralization of Special Elements used in an OS Command), commonly known as OS Command Injection. The flaw exists in myPRO Manager's input handling mechanism where user-supplied data passed to a command parameter is not properly sanitized before being incorporated into operating system commands.
The network-accessible nature of this vulnerability combined with the absence of authentication requirements makes it particularly dangerous for internet-exposed or poorly segmented industrial environments. An attacker can craft malicious requests containing shell metacharacters or command sequences that are then executed with the privileges of the myPRO Manager service.
Root Cause
The root cause of CVE-2024-47407 stems from insufficient input validation on a command parameter within myPRO Manager. The application fails to properly sanitize or escape special characters before passing user input to system shell commands. This allows attackers to break out of the intended command context and inject additional commands using shell metacharacters such as semicolons (;), pipes (|), backticks, or command substitution syntax.
Attack Vector
The attack vector is network-based and requires no authentication or user interaction. An attacker with network access to a vulnerable myPRO Manager instance can send specially crafted requests containing malicious command injection payloads. The injected commands execute in the context of the myPRO Manager process, typically granting the attacker significant control over the underlying host system.
In ICS/SCADA environments, successful exploitation could enable attackers to:
- Gain persistent access to industrial control networks
- Manipulate or disable critical monitoring and control systems
- Pivot to other connected industrial devices
- Exfiltrate sensitive operational data
For technical details regarding the vulnerability mechanism, refer to the CISA ICS Advisory ICSA-24-326-07.
Detection Methods for CVE-2024-47407
Indicators of Compromise
- Unexpected outbound network connections from myPRO Manager servers to unknown destinations
- Unusual process spawning from the myPRO Manager service (e.g., cmd.exe, bash, sh, powershell)
- Anomalous command-line arguments in process logs containing shell metacharacters
- Suspicious HTTP requests with encoded or special characters targeting myPRO Manager endpoints
Detection Strategies
- Deploy network intrusion detection signatures to identify command injection patterns in traffic destined for myPRO Manager
- Monitor web application firewall (WAF) logs for requests containing common injection characters such as ;, |, &, backticks, and $() sequences
- Implement endpoint detection rules to alert on child process creation from myPRO Manager services
- Review authentication logs for any access attempts from unauthorized IP ranges
Monitoring Recommendations
- Enable comprehensive logging on myPRO Manager and forward logs to a centralized SIEM platform
- Configure alerts for any network traffic to myPRO Manager from untrusted network segments
- Establish baseline behavior for myPRO Manager processes and alert on deviations
- Monitor for lateral movement attempts originating from hosts running myPRO Manager
How to Mitigate CVE-2024-47407
Immediate Actions Required
- Isolate myPRO Manager instances from direct internet access immediately
- Implement network segmentation to restrict access to myPRO Manager from authorized management networks only
- Apply vendor-provided patches as soon as they become available
- Review and audit all access logs for signs of exploitation attempts
- Enable web application firewall protections in front of myPRO Manager deployments
Patch Information
Organizations should consult the CISA ICS Advisory ICSA-24-326-07 for official patch information and vendor guidance from mySCADA. It is critical to apply patches in accordance with your organization's change management procedures while prioritizing remediation given the critical severity of this vulnerability.
Workarounds
- Restrict network access to myPRO Manager to only trusted IP addresses using firewall rules or access control lists
- Deploy a reverse proxy or web application firewall with command injection protection rules in front of myPRO Manager
- If possible, disable or restrict the vulnerable functionality until patches can be applied
- Implement additional authentication layers such as VPN requirements for accessing myPRO Manager interfaces
# Example firewall rule to restrict myPRO Manager access (Linux iptables)
# Allow access only from trusted management network 10.10.10.0/24
iptables -A INPUT -p tcp --dport 443 -s 10.10.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
