CVE-2025-2727

8.0 HIGH

📋 TL;DR

This critical vulnerability in H3C Magic NX30 Pro routers allows attackers on the local network to execute arbitrary commands via a command injection flaw in the HTTP POST request handler for the /api/wizard/getNetworkStatus endpoint. It affects users of H3C Magic NX30 Pro routers up to version V100R007, potentially leading to full device compromise. Exploitation requires local network access, limiting exposure to internal attackers or those who have breached the network perimeter.

💻 Affected Systems

Products:
  • H3C Magic NX30 Pro
Versions: Up to V100R007
Operating Systems: Embedded router firmware
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability is in the default configuration of the affected firmware versions; no special settings are required for exploitation.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full compromise of the router, enabling persistent remote access, data interception, network pivoting to other devices, and disruption of network services.

🟠

Likely Case

Unauthorized command execution leading to configuration changes, data theft, or installation of malware on the router.

🟢

If Mitigated

Limited impact if network segmentation isolates the router and strict access controls are enforced, though local attackers could still exploit it.

🌐 Internet-Facing: LOW, as the vulnerability requires access to the local network; direct internet exploitation is not possible unless the router's admin interface is exposed to the internet, which is not typical.
🏢 Internal Only: HIGH, because attackers on the local network can exploit it to gain control of the router, posing significant risk to internal security.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploit details are publicly disclosed, but exploitation requires crafting specific HTTP POST requests to the vulnerable endpoint, which may involve some technical skill.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Versions after V100R007 (specific version not specified in references; upgrade to latest available)

Vendor Advisory: https://www.h3c.com/cn/Service/Document_Software/Software_Download/Consume_product/

Restart Required: No

Instructions:

1. Access the H3C Magic NX30 Pro router's admin interface. 2. Navigate to the firmware update section. 3. Download the latest firmware from the vendor's official website. 4. Upload and apply the firmware update. 5. Verify the update completes successfully.

🔧 Temporary Workarounds

Restrict Access to Router Admin Interface

all

Limit network access to the router's admin interface to trusted IP addresses only, reducing exposure to potential attackers.

Configure firewall rules to block external access to port 80/443 except from authorized management IPs.

🧯 If You Can't Patch

  • Isolate the router on a dedicated VLAN to limit lateral movement in case of exploitation.
  • Monitor network traffic for unusual HTTP POST requests to /api/wizard/getNetworkStatus and implement intrusion detection rules.

🔍 How to Verify

Check if Vulnerable:

Check the router's firmware version via the admin interface; if it is V100R007 or earlier, it is vulnerable.

Check Version:

Log into the router's web interface and navigate to System Status or similar section to view firmware version.

Verify Fix Applied:

After updating, verify the firmware version is above V100R007 and test by attempting to send a crafted POST request to /api/wizard/getNetworkStatus to ensure no command execution occurs.

📡 Detection & Monitoring

Log Indicators:

  • Unusual HTTP POST requests to /api/wizard/getNetworkStatus with shell command patterns in parameters.
  • Log entries showing command execution or system changes from unknown sources.

Network Indicators:

  • HTTP traffic to the router's IP on port 80/443 containing suspicious strings like ';', '|', or '`' in POST data.

SIEM Query:

source="router_logs" AND url="/api/wizard/getNetworkStatus" AND (method="POST") AND (data CONTAINS "cmd" OR data CONTAINS ";" OR data CONTAINS "|")
