Overview
The potential compromise of network security is a grave concern in the modern digital world. One such threat is the recently discovered vulnerability in the KuWFi 4G LTE AC900 router, identified as CVE-2024-53946. This vulnerability is of particular significance due to its potential to compromise system security and leak sensitive data.
The vulnerability affects KuWFi 4G LTE AC900 routers running on version 1.0.13. The issue resides in the web management interface of these devices, allowing an attacker to run unauthorized commands and alter the configuration of the device without the admin’s knowledge. The exploitation of this vulnerability could lead to severe consequences, including system compromise and data leakage.

How the Exploit Works
The exploit takes advantage of a Cross-Site Request Forgery (CSRF) vulnerability in the router’s web management interface. By tricking an authenticated admin user into clicking a malicious link or opening a compromised file, an attacker can run unauthorized commands through /goform/formMultiApnSetting. This can lead to unauthorized configuration changes and potentially compromise the entire system or leak sensitive data.
Conceptual Example Code
Consider the following hypothetical example showing how an attacker might exploit this vulnerability through a maliciously crafted HTTP request:
POST /goform/formMultiApnSetting HTTP/1.1
Host: target.router.com
Content-Type: application/json
{
"command": "reboot; rm -rf /*; echo 'System compromised!'"
}In this example, the attacker sends a POST request to the vulnerable endpoint (`/goform/formMultiApnSetting`). The command injected could lead to a reboot of the system and deletion of all files, indicating a total system compromise.
Mitigation Measures
To mitigate this vulnerability, the recommended course of action is to apply the vendor patch as soon as it is available. In the interim, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can offer temporary protection by blocking or alerting on suspicious network traffic. Always ensure that your network devices, including routers, are kept up-to-date with the latest firmware and security patches to reduce the risk of exploitation.
