A new critical vulnerability (CVE-2025-25728) has been discovered in Bosscomm IF740 Firmware, posing a significant security risk to the devices and users. The affected firmware versions are v11001.7078 and v11001.000, and system versions 6.25 and 6.00. This vulnerability allows attackers to access sensitive device information through plaintext communication and perform a man-in-the-middle (MITM) attack. In this post, we will delve deeper into the details, including the code snippet, links to relevant references, and exploit information.

Vulnerability Details

Bosscomm IF740 Firmware versions v11001.7078 and v11001.000, and system versions 6.25 and 6.00, were found to be sending communication to the update API in plaintext. The problem arises due to the lack of encryption (HTTPS) in the communication sent to the API. Consequently, an attacker can intercept the transmitted sensitive data, gaining unauthorized access to crucial information.

Below is a code snippet demonstrating the plaintext HTTP communication

import requests

url = "http://update.api.bosscomm.com/device/check_update";
data = {
    "device_id": "123456789",
    "firmware_version": "v11001.7078",
    "system_version": "6.25"
}

response = requests.post(url, data=data)
print(response.text)

In the above Python code snippet, the communication and data exchange with the update API occur over plaintext HTTP. This allows any attacker with the ability to intercept the communication to retrieve sensitive data using a MITM attack.

Exploit Details

The primary exploitation method for this vulnerability is a MITM attack. An attacker could intercept the plaintext communication between the update API and the affected firmware versions and gain access to sensitive information such as device IDs, firmware versions, and system versions. This information can then be utilized to conduct further attacks, posing a potential risk to the user's privacy and data security.

To perform a MITM attack, an attacker could use various techniques and tools, such as ARP spoofing tools like Ettercap and Wireshark, or DNS spoofing or manipulation.

The following steps can be undertaken to mitigate the risk posed by CVE-2025-25728

1. Update your Bosscomm IF740 Firmware to the latest version. Visit the Bosscomm IF740 Official Support Page for the latest updates.
2. Implement secure communication to the update API using HTTPS encryption to protect sensitive data from being intercepted.

Regularly monitor and assess your network for potential threats and vulnerabilities.

4. Stay informed about security patches and updates by subscribing to security mailing lists, forums, and following trusted sources.

Conclusion

CVE-2025-25728 poses a critical risk to the Bosscomm IF740 Firmware versions v11001.7078 and v11001.000, and system versions 6.25 and 6.00 by allowing attackers to access sensitive information through a MITM attack. By understanding the CVE, its exploit, and taking necessary precautions and updates, users can minimize the risk and protect their data privacy and security.
