How the Exploit Works

The vulnerability lies in the function Edit_List_SSID of the file /goform/aspForm. A malicious actor can manipulate the argument param, leading to a buffer overflow condition. This buffer overflow could allow an attacker to execute arbitrary code or cause a denial of service (DoS) condition leading to system compromise and potential data leakage.

Conceptual Example Code

This conceptual HTTP request illustrates how the vulnerability might be exploited:

POST /goform/aspForm HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "param": "OVERFLOW_STRING" }

In this example, the OVERFLOW_STRING would be a carefully crafted string designed to overflow the buffer, leading to potential system compromise or data leakage.

Mitigation Guidance

As a solution to this vulnerability, it is recommended to apply the vendor patch immediately. In case the patch cannot be applied immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method. These tools can help monitor network traffic and detect potential exploitation attempts of this vulnerability.
In conclusion, CVE-2025-4446 poses a significant threat to any network running the H3C GR-5400AX, up to version 100R008. To maintain the security and integrity of your systems, it is critically important to apply the vendor patch or employ temporary mitigation techniques as soon as possible.
