CVE-2025-3544: Critical Command Injection Vulnerability in H3C Magic Series

Overview

A critical security vulnerability, tagged as CVE-2025-3544, has been discovered in a number of H3C Magic products, namely the NX15, NX30 Pro, NX400, R3010, and BE18000. This vulnerability specifically affects versions up to V100R014 of these products. This vulnerability, which has been classified as critical, impacts the way these systems handle HTTP POST requests, leading to possible command injection. An attacker with access to the local network can potentially compromise the system or cause data leakage. Given the severity of this vulnerability, it’s crucial that IT professionals managing these systems take immediate steps to mitigate the risk.

How the Exploit Works

The vulnerability resides in the FCGI_CheckStringIfContainsSemicolon function of the /api/wizard/getCapabilityWeb file. The component responsible for handling HTTP POST requests fails to properly sanitize inputs, allowing an attacker to inject commands. When a specially crafted request is sent to the affected component, the system processes the malicious command, potentially leading to unauthorized system access or data exfiltration.

Conceptual Example Code

Here is a conceptual representation of how a malicious HTTP request might be structured to exploit this vulnerability:

POST /api/wizard/getCapabilityWeb HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "command": "; rm -rf / --no-preserve-root" }

In this hypothetical example, the attacker is attempting to inject a command to delete all files on the system. This is a conceptual example; the actual exploit may vary based on the specific system configuration and the attacker’s objectives.

Recommended Mitigation

Users are advised to apply the vendor patch as soon as possible. If a patch cannot be immediately applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Regularly updating and patching systems, as well as monitoring network activity for signs of unusual behavior, can help prevent successful exploitation of this vulnerability.
