Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation of Remote Services (T1210); ranked in the top 44.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the CVE by requiring timely firmware upgrades to patch the command injection vulnerability in the affected H3C router models.
Prevents command injection by enforcing input validation and sanitization mechanisms on HTTP POST requests to the vulnerable /api/wizard/getDualbandSync endpoint.
Limits exploitation from the adjacent local network by monitoring and controlling access to the vulnerable HTTP management API endpoint.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The CVE describes a command injection vulnerability in a router's HTTP API endpoint, allowing arbitrary command execution via crafted POST requests from an adjacent network. This directly maps to exploitation of remote services (T1210) and command execution via Unix shell (T1059.004).
NVD Description
A vulnerability was found in H3C Magic NX15, Magic NX30 Pro, Magic NX400, Magic R3010 and Magic BE18000 up to V100R014. It has been declared as critical. Affected by this vulnerability is an unknown functionality of the file /api/wizard/getDualbandSync of…

the component HTTP POST Request Handler. The manipulation leads to command injection. The attack needs to be done within the local network. The exploit has been disclosed to the public and may be used. It is recommended to upgrade the affected component.
Deeper analysisAI
CVE-2025-2731 is a critical command injection vulnerability (CVSS 8.0, CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) discovered in H3C Magic NX15, Magic NX30 Pro, Magic NX400, Magic R3010, and Magic BE18000 routers up to version V100R014. The issue resides in an unknown functionality of the /api/wizard/getDualbandSync endpoint within the HTTP POST Request Handler component and is linked to CWE-74 and CWE-77. Published on 2025-03-25, it enables manipulation via crafted POST requests.
An attacker on the adjacent local network with low privileges can exploit this vulnerability by sending a malicious HTTP POST request to the affected endpoint, requiring low complexity and no user interaction. Successful exploitation leads to arbitrary command injection, granting high-impact compromise of confidentiality, integrity, and availability on the targeted device.
Advisories recommend upgrading the affected component to a patched version as the primary mitigation. Details are available via VulDB entries and the H3C software download portal for relevant firmware updates.
The exploit has been publicly disclosed and may be actively used by attackers.
