Sometimes, vulnerabilities seem to slip through the cracks despite developers' best efforts to keep their applications secure. One such vulnerability has recently come to light in the form of CVE-2020-13712, a command injection vulnerability affecting OMG200 and MG90 devices running older versions of MGOS. This security vulnerability allows an attacker to execute arbitrary commands as the root user through the devices' user interface.
In this long read post, we'll discuss the CVE-2020-13712 vulnerability as it pertains to OMG200 and MG90 devices, including details about the exploit, as well as provide some resources for further investigation.
MG90 running MGOS versions 4.2.1 or earlier
If your device runs one of the aforementioned versions, your network is potentially at risk and immediate action is necessary.
Exploit Details
The vulnerability lies in the user interface of the affected devices. An attacker can potentially inject malicious commands, effectively allowing arbitrary command execution as the root user. The execution of arbitrary commands on a device in a network can lead to a wide range of consequences, including remote code execution, denial of service, and data breaches.
Following is a simple example of exploiting this vulnerability using Python
import requests
target_url = "http://<IP_ADDRESS_OF_DEVICE>/path/to/vulnerable/endpoint";
# Replace <IP_ADDRESS_OF_DEVICE> with the actual IP address of the target OMG200 or MG90 device.
# Replace <COMMAND_TO_EXECUTE> with the desired command to be executed as the root user.
payload = {"command": "<COMMAND_TO_EXECUTE>;"}
response = requests.post(target_url, data=payload)
By initializing a POST request to the target URL with the malicious payload (command), it is possible to achieve arbitrary command execution as the root user. Given the heightened privileges, an attacker can potentially wreak havoc on affected networks.

Mitigation
To protect your devices and network from this vulnerability, it is recommended to update the MGOS firmware on your OMG200 and/or MG90 devices immediately. By updating to the latest version, you can eliminate the risk of arbitrary command execution through the user interface. Additionally, it is always a good practice to monitor the security landscape for emerging threats and routinely update your devices to ensure the most up-to-date protection is in place.
Conclusion
CVE-2020-13712 presents a significant risk to OMG200 and MG90 devices running MGOS versions 3.15.1 or earlier and 4.2.1 or earlier, respectively. This vulnerability allows for arbitrary command execution as the root user, which can lead to considerable damage. We strongly recommend taking steps to mitigate this vulnerability by updating the firmware on affected devices and maintaining awareness of emerging security threats.
