How the Exploit Works

The vulnerability lies in the web_acl_bindEdit_post function of the FW-WGS-804HPT product’s code. This function fails to properly handle user-supplied input in the bindEditMACName parameter. An attacker can exploit this by sending a specially crafted request to this function, which can cause a stack overflow. This overflow can give the attacker the ability to execute arbitrary code or commands, potentially leading to system compromise or data leakage.

Conceptual Example Code

Here is a conceptual example of how the attack might be carried out:

POST /web_acl_bindEdit_post HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "bindEditMACName": "AAAAAAAA...[STACK OVERFLOW]...AAAA" }

In this example, the attacker sends a POST request to the vulnerable endpoint with a large amount of data in the ‘bindEditMACName’ parameter, causing a stack overflow.

Mitigation

Until an official patch is released by the vendor, organizations can use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability. Implementing strict input validation on the bindEditMACName parameter can also help in preventing this type of attack.
However, these are only temporary solutions. For long-term security, it is recommended to apply the vendor patch as soon as it becomes available, and always keep your systems updated with the latest security patches and updates.
