How to remediate – AirConnect Default Password

1. Introduction

The AirConnect Default Password vulnerability allows unauthorized access to remote wireless access points using default credentials. This could allow an attacker to gain full control over a wireless network, potentially compromising sensitive data and disrupting service availability. Systems affected are typically AirConnect wireless access points with factory settings still in place. Impact on confidentiality is high due to potential data breaches, integrity is high as attackers can modify configurations, and availability is medium due to possible denial of service or disruption.

2. Technical Explanation

• Root cause: Use of a weak, publicly known default password for administrative access.
• Exploit mechanism: An attacker attempts to log in to the web interface with default credentials (often ‘admin/admin’ or similar). Successful login grants full control over the device and network settings.
• Scope: AirConnect wireless access points using the default firmware configuration.

3. Detection and Assessment

To confirm vulnerability, check if the web interface is accessible with default credentials. A thorough method involves attempting to enumerate the device’s configuration via a network scan.

• Quick checks: Attempt to access the AirConnect web interface using common default usernames and passwords (e.g., admin/admin).
• Scanning: Nmap can be used with scripts like http-default-accounts to identify devices responding with default credentials. Example: nmap -p 80 --script http-default-accounts
• Logs and evidence: Check web server logs for login attempts using default usernames. Event IDs may vary depending on the access point model.

Attempt to connect to the AirConnect web interface via a browser with username 'admin' and password 'admin'. If successful, the device is vulnerable.

4. Solution / Remediation Steps

The solution involves changing the default password to something difficult to guess through the web interface. Follow these steps carefully.

4.1 Preparation

• Change window needs: This change should be performed during off-peak hours with approval from the IT security team.

4.2 Implementation

1. Step 1: Log in to the AirConnect web interface using the default credentials (if possible).
2. Step 2: Navigate to the “Administration” or “System Settings” section of the web interface. The exact location varies by model.
3. Step 3: Locate the password change option and enter a strong, unique password.
4. Step 4: Save the changes and verify that you can log in with the new credentials.

4.3 Config or Code Example

Before

Default username: admin
Default password: admin

After

Username: 
Password: 

4.4 Security Practices Relevant to This Vulnerability

Practices that directly address this vulnerability type include secure defaults and least privilege. Least privilege reduces the impact if an attacker gains access, while strong passwords prevent unauthorized login attempts.

• Practice 2: Enforce strong password policies with minimum length and complexity requirements.

4.5 Automation (Optional)

Automation is not typically suitable for this specific vulnerability due to the need for manual interaction with the web interface. However, configuration management tools could be used to periodically check for default credentials on managed devices.

# Example script using SSH and a configuration file to check password (not recommended for direct execution without careful testing)

5. Verification / Validation

Confirm the fix by attempting to log in with the old, default credentials. A successful login attempt indicates the fix has failed. Also perform basic service smoke tests.

• Post-fix check: Attempt to log in to the AirConnect web interface using the default username and password (e.g., admin/admin). Expected output: Login failure.
• Re-test: Repeat the quick checks from Section 3, confirming that default credentials no longer work.
• Monitoring: Monitor web server logs for failed login attempts using default usernames as an indicator of potential attacks.

Attempt to log in with 'admin/admin'. Expected output: "Invalid username or password."

6. Preventive Measures and Monitoring

• Baselines: Update your network device baseline or CIS control settings to require immediate password changes.
• Pipelines: Add a check in your deployment process to scan for default credentials on newly deployed AirConnect devices.

7. Risks, Side Effects, and Roll Back

Changing the password incorrectly could lock you out of the device. Always document the new password securely. If locked out, a factory reset may be required.
