CVE-2025-2727

Remediation/Mitigation Strategy: CVE-2025-2727 - H3C Magic NX30 Pro Command Injection

Vulnerability Description:

  • CVE ID: CVE-2025-2727
  • Vulnerability Name: H3C Magic NX30 Pro Command Injection
  • Affected Product: H3C Magic NX30 Pro
  • Affected Version: Up to V100R007
  • Vulnerability Location: /api/wizard/getNetworkStatus (HTTP POST Request Handler)
  • Vulnerability Type: Command Injection
  • Description: A critical command injection vulnerability exists in the HTTP POST Request Handler for the /api/wizard/getNetworkStatus endpoint of H3C Magic NX30 Pro devices up to version V100R007. By manipulating input parameters in the HTTP POST request, an attacker can inject and execute arbitrary commands on the underlying operating system of the device.

Severity:

  • CVSS Score: 9.0 (Critical)
  • Severity Level: Critical
  • Impact: Successful exploitation of this vulnerability allows an attacker to gain complete control over the affected device. This includes the ability to:
    • Execute arbitrary commands as root.
    • Modify device configuration.
    • Install malicious software.
    • Pivot to other devices on the network.
    • Cause a denial-of-service.
    • Exfiltrate sensitive data.

Known Exploit:

  • Exploit Availability: Publicly Available. The report indicates an exploit has been disclosed to the public and may be used. This significantly increases the risk of exploitation.

Remediation/Mitigation Strategy:

Given the critical severity and the existence of a public exploit, immediate action is required.

1. Patching (Recommended):

  • Vendor Patch: The ideal solution is to apply a security patch provided by H3C. However, the report notes that the vendor was contacted but did not respond. Continuously monitor H3C’s website and security advisories for any updates or patches. If a patch is released, apply it immediately following thorough testing in a non-production environment.

2. Workarounds/Mitigation (If no patch is available):

Since a patch might not be available due to the vendor’s non-responsiveness, implement the following workarounds immediately:

  • Network Segmentation: Isolate the H3C Magic NX30 Pro device from the rest of the network. Place it behind a firewall and restrict access to only necessary services and personnel.
  • Access Control: Implement strict access control lists (ACLs) on the firewall to limit access to the device’s management interface and the vulnerable /api/wizard/getNetworkStatus endpoint. Only allow trusted IP addresses or networks to access the device.
  • Web Application Firewall (WAF): If a WAF is deployed, create a rule to inspect traffic to /api/wizard/getNetworkStatus for suspicious payloads and patterns indicative of command injection attempts. Block any requests that match these patterns. Common command injection payloads involve characters like |, ;, &, $(), etc.
  • Input Validation (Implement on any systems interacting with the H3C Device): If any internal applications interact with the vulnerable API endpoint, implement rigorous input validation. Sanitize all input received from the H3C device to prevent the injection of malicious commands.
  • Disable Remote Access (if possible): If the device does not require remote access, disable it entirely. This will reduce the attack surface and make it more difficult for attackers to exploit the vulnerability.
  • Monitor Logs: Enable comprehensive logging on the H3C Magic NX30 Pro device and the surrounding network infrastructure. Monitor the logs for any suspicious activity, such as unauthorized access attempts, unusual network traffic, or command injection attempts. Correlate logs with network intrusion detection systems (IDS) and intrusion prevention systems (IPS).
  • Intrusion Detection/Prevention Systems (IDS/IPS): Configure IDS/IPS systems to detect and block command injection attempts targeting the /api/wizard/getNetworkStatus endpoint.
  • Rate Limiting: Implement rate limiting on the /api/wizard/getNetworkStatus endpoint to prevent attackers from flooding the device with malicious requests.

3. Long-Term Strategy:

  • Device Replacement: Given the vendor’s lack of responsiveness and the critical nature of the vulnerability, consider replacing the H3C Magic NX30 Pro device with a more secure alternative from a vendor that provides timely security updates.
  • Vendor Risk Assessment: Evaluate the security practices and response times of vendors before purchasing network devices. Prioritize vendors with a proven track record of providing timely security updates and responding to security vulnerabilities.
  • Regular Vulnerability Scanning: Implement a regular vulnerability scanning program to identify and remediate security vulnerabilities in network devices and other systems.
  • Security Awareness Training: Provide security awareness training to employees to help them recognize and avoid phishing attacks and other social engineering tactics that could be used to gain access to the network.

4. Monitoring and Verification:

  • Continuously monitor the effectiveness of the implemented mitigation measures.
  • Regularly review logs and security alerts to identify and respond to potential attacks.
  • After implementing mitigation, perform penetration testing to verify that the vulnerability has been effectively addressed.

Important Considerations:

  • Due to the vendor’s non-responsiveness, a permanent fix may not be available. The suggested workarounds are designed to reduce the risk of exploitation, but they may not eliminate it completely.
  • It is crucial to prioritize the remediation of this vulnerability due to its critical severity and the availability of a public exploit.
  • The effectiveness of the mitigation measures depends on the specific network environment and security configuration. Tailor the mitigation strategy to the unique characteristics of your organization.
  • This vulnerability highlights the importance of choosing reputable vendors with a strong commitment to security.

This remediation/mitigation strategy should be reviewed and updated regularly as new information becomes available.
