SUMMARY

CVE-2024-9404: Denial-of-Service Vulnerability Identified in Multiple EDS, ICS, IKS, and SDS Switches

  • Security Advisory ID: MPSA-240931
  • Version: V1.2
  • Release Date: Feb 07, 2025
  • Reference:

    CVE-2024-9404 (Moxa) 

Multiple Moxa EDS, ICS, IKS, and SDS switches are affected by a high-severity vulnerability, CVE-2024-9404, which could lead to a denial-of-service condition or cause a system or service crash. This vulnerability allows attackers to exploit the Moxa service, commonly referred to as moxa_cmd, originally designed for deployment purposes. Due to insufficient input validation, this service can be exploited to trigger a cold start or denial-of-service condition.

This vulnerability poses a significant remote threat if the affected products are exposed to publicly accessible networks. Attackers could potentially disrupt operations by shutting down the affected systems. Due to the critical nature of this security risk, we strongly recommend taking immediate action to prevent its potential exploitation. 

The Identified Vulnerability Type and Potential Impact 

Vulnerability Type Impact

CWE-1287: Improper Validation of Specified Type of Input (CVE-2024-9404) 

 This vulnerability (CVE-2024-9404) could lead to denial-of-service or service crashes. Exploitation of the moxa_cmd service, because of insufficient input validation, allows attackers to disrupt operations. If exposed to public networks, the vulnerability poses a significant remote threat, potentially allowing attackers to shut down affected systems.

Mitigations

To mitigate the risks associated with this vulnerability, we recommend the following actions: 

  • Disable Moxa Service and Moxa Service (Encrypted) temporarily if they are not required for operations. This will minimize potential attack vectors until a patch or updated firmware is applied. 

Refer to the General Security Recommendations section to further strengthen your security posture. 

 

General Security Recommendations

To safeguard devices and networks, we recommend implementing the following recommendations to mitigate potential risks:

  1. Restrict Network Access
    • Use firewalls or access control lists (ACLs) to limit communication to trusted IP addresses and networks.
    • Segregate operational networks from other networks (e.g., enterprise networks) using VLANs or physical separation.
  2. Minimize Exposure
    • Avoid exposing devices directly to the Internet.
    • Disable unused network services and ports to reduce the attack surface.
  3. Enhance Device Authentication and Access Control
    • Implement multi-factor authentication (MFA) for accessing critical systems.
    • Use role-based access control (RBAC) to enforce the principle of least privilege.
  4. Regularly Update Firmware and Software
    • Keep devices updated with the latest firmware versions and security patches.
    • Establish a regular patch management schedule to address newly identified vulnerabilities.
  5. Secure Remote Access
    • Use encrypted communication protocols (e.g., VPN, SSH) for remote access.
    • Restrict remote access to authorized personnel only and enforce strong authentication mechanisms.
  6. Implement Anomaly Detection Techniques
    • Monitor network traffic and device behavior for unusual or unauthorized activities.
    • Use tools or techniques that can identify anomalies and provide alerts for potential threats.
  7. Implement Logging and Monitoring
    • Enable event logging and maintain audit trails on devices.
    • Regularly review logs for anomalies and unauthorized access attempts.
  8. Conduct Regular Security Assessments
    • Perform vulnerability assessments to identify potential risks.
    • Regularly review device configurations to ensure compliance with security policies.
