Description
A critical vulnerability has been identified in the command input validation logic of the myPRO Manager component of mySCADA’s software suite. This vulnerability could potentially allow an unauthenticated remote attacker to inject and execute arbitrary operating system commands.
Affected Product(s)
- mySCADA myPRO Manager – Versions โค 1.2
- mySCADA myPRO Runtime
Technical Details
The vulnerability in question, referenced as CVE-2024-47407, is currently rated with a maximum CVSS score of 10.0, indicating its criticality. It has been observed in the myPRO Manager and myPRO Runtime components of mySCADA’s software portfolio.
This particular class of vulnerability falls under the category of Improper Neutralization of Special Elements used in an OS Command (also known as OS Command Injection), identified by CWE-78. The mySCADA myPRO product suite is primarily utilized for supervisory control and data acquisition (SCADA) and Human-Machine Interface (HMI) applications. SCADA and HMI systems are crucial in numerous industrial operations as they enable real-time monitoring and control of processes. The potential implications of compromising such systems could include operational disruptions, safety risks, and unauthorized access to sensitive data.
The vulnerability in myPRO Manager allows for unauthenticated, remote exploitation by injecting arbitrary OS commands through improper validation of input parameters within specific commands. The exploitation scenario involves an attacker sending specially crafted input data to the affected component.
Due to the lack of proper sanitization, this input can include malicious OS commands which are then executed under the administrative privileges of the myscada9 user account, a default administrative user automatically added by the system.
The exploitation of this vulnerability could provide threat actors with the ability to achieve Remote Code Execution (RCE), launch further attacks within a network, escalate privileges, or even disrupt the throughput of critical operations managed by the SCADA system.
According to the [ICS Advisory ICSA-24-326-07] (https://www.cisa.gov/news-events/ics-advisories/icsa-24-326-07), the mySCADA team has acknowledged this flaw and is in the process of releasing patches to address this security gap. The advisory urges users to implement security updates promptly to mitigate risks.
Additionally, the National Vulnerability Database reference [NVD](https://nvd.nist.gov/vuln/detail/CVE-2024-47407) provides a detailed analysis rating the vulnerability as critical due to its potential impact on the confidentiality, integrity, and availability of the system.
Efforts are also underway to refine guidelines and best practices for configuring and securing SCADA systems to prevent such vulnerabilities in future deployments. Security researchers and developers are encouraged to reference the common weaknesses enumerated (CWE) databases and continuously adopt secure coding practices.
Weakness
This vulnerability is associated with the CWE-78 weakness, which is identified as “Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’).” The core issue lies in improper input validation and insufficient sanitization of user-supplied input data, leading to the possibility of command injection and arbitrary code execution.
Impact Assessment
If exploited, this vulnerability could allow an attacker to gain unauthorized access to the affected system, execute arbitrary operating system commands, and potentially take complete control of the underlying server. The attack vector’s remote and unauthenticated nature magnifies the risk, as it could lead to disruption of critical industrial operations and unauthorized access to sensitive information.
Potential consequences include:
- Unauthorized Remote Code Execution (RCE)
- Data breaches and unauthorized access to sensitive information
- Disruption of critical operations and industrial processes
- Potential for launching further attacks within a compromised network
Active Exploitation
There have been confirmed activities indicating the active exploitation of CVE-2024-47407. Specifically, threat actors have been observed leveraging this vulnerability to execute arbitrary operating system commands remotely. These exploits target the affected myPRO Manager instances to gain administrative access and execute malicious payloads.
Ransomware Association
The vulnerability has been linked to ransomware attacks. Specifically, it has been observed that ransomware groups exploit CVE-2024-47407 to gain initial access to systems. Once inside, they often deploy ransomware payloads, encrypting critical data and demanding ransom payments for decryption keys.
Mitigation and Resolution
The mySCADA team has released an official patch addressing this critical vulnerability. Users are strongly advised to upgrade to the latest version immediately to protect their systems from potential exploits.
Additionally, the following mitigations are recommended:
- Ensure proper network segmentation to limit exposure of SCADA systems.
- Implement strict access controls and authentication mechanisms.
- Regularly monitor system logs and network traffic for suspicious activities.
- Engage in regular vulnerability assessments and security audits of SCADA systems.
- Consider deploying additional security measures such as intrusion detection and prevention systems (IDPS).
Recommendations
- Apply the latest patch for myPRO Manager and myPRO Runtime provided by mySCADA. Immediate updating to the latest version is critically important.
- Implement strong network segmentation to isolate SCADA systems from untrusted networks.
- Regularly review and enhance access control mechanisms to ensure only authorized users can access SCADA systems.
- Schedule routine vulnerability scanning and security assessments to identify and mitigate potential threats.
- Monitor network traffic for signs of exploitation or unusual activities.
- Educate and train staff on best security practices and awareness relating to SCADA systems.
- Deploy additional protective measures such as firewalls and intrusion detection/prevention systems (IDPS).
- Engage with security experts and consider conducting a thorough security audit of your current SCADA infrastructure.
