CVE-2025-3541: Critical Command Injection Vulnerability in H3C Magic Series

Overview

Recently, a critical vulnerability has been discovered in the H3C Magic NX15, Magic NX30 Pro, Magic NX400, and Magic R3010 devices up to V100R014. This vulnerability poses a significant risk to the integrity, confidentiality, and availability of the systems within the local network. The flaw resides in the HTTP POST Request Handler’s function FCGI_WizardProtoProcess of the file /api/wizard/getSpecs, and it allows for command injection. Its public disclosure means that threat actors may be actively exploiting it, highlighting the urgent need for remediation.

Vulnerability Summary

CVE ID: CVE-2025-3541

Affected Products

Product | Affected Versions

H3C Magic NX15 | Up to V100R014
H3C Magic NX30 Pro | Up to V100R014
H3C Magic NX400 | Up to V100R014
H3C Magic R3010 | Up to V100R014

How the Exploit Works

The vulnerability resides in the FCGI_WizardProtoProcess function of the /api/wizard/getSpecs file. By manipulating the HTTP POST Request Handler, an attacker can inject malicious commands into the system. This attack must be executed within the local network, indicating that the threat actor needs to have access to the same network as the target devices.

Conceptual Example Code

The following is a conceptual example of how the vulnerability might be exploited. An attacker sends a malicious HTTP POST request to the vulnerable endpoint:

POST /api/wizard/getSpecs HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "payload": "INJECTED_COMMAND_HERE" }

Here, `INJECTED_COMMAND_HERE` would be replaced with the actual malicious command aimed at compromising the system or exfiltrating data.

Remediation

To address this critical vulnerability, it is highly recommended to immediately apply the vendor-provided patch. In case updating is not possible immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation until the patch can be applied. Regularly updating and patching systems is a crucial aspect of maintaining a robust security posture.
This vulnerability serves as a reminder of the importance of maintaining a rigorous cybersecurity stance, including regular patching and updating of all systems and software.
