How to remediate – Ubiquiti airCam Detection

1. Introduction

The Ubiquiti airCam Detection identifies systems running Ubiquiti airCam IP cameras. These devices are commonly used for surveillance but have known security weaknesses. A successful exploit could allow an attacker to view the camera feed, change settings, or gain access to the network it’s connected to. This impacts confidentiality, integrity and availability of video data and potentially wider network resources.

2. Technical Explanation

The vulnerability stems from Ubiquiti airCam cameras being identifiable as a specific device type. While not an active exploit in itself, this identification allows attackers to specifically target these devices with known exploits or default credentials. There is no CVE currently associated with this detection; it’s primarily a reconnaissance finding. An attacker could scan the internet for airCams and attempt brute-force attacks against common usernames and passwords. All Ubiquiti airCam models are affected.

• Root cause: The devices are easily identifiable by network scanning tools.
• Exploit mechanism: Attackers use port scans to identify the cameras, then attempt default credential attacks or known exploits.
• Scope: All Ubiquiti airCam IP camera models.

3. Detection and Assessment

You can confirm if a system is vulnerable by identifying whether it presents as an Ubiquiti airCam device. A quick check involves looking at the device’s web interface or using network scanning tools to identify its manufacturer and model.

• Quick checks: Access the camera’s web interface (usually via a browser) and look for “Ubiquiti” in the branding or about section.
• Scanning: Nmap can be used with the following script: nmap -p 80,443 --script http-title Look for “Ubiquiti” in the output title. This is an example only.
• Logs and evidence: Check network device logs for connections to or from IP addresses associated with Ubiquiti airCam devices.

4. Solution / Remediation Steps

The primary solution is to secure the camera and ensure it’s not directly exposed to the internet. This involves changing default credentials, updating firmware, and implementing network segmentation.

4.1 Preparation

• Ensure you have access to the camera’s web interface and know the current credentials. A roll back plan involves restoring the backed-up configuration.
• A change window is recommended, especially for production systems. Approval from a security team lead might be needed.

4.2 Implementation

1. Step 1: Change the default username and password to strong, unique values.
2. Step 2: Update the camera’s firmware to the latest version available from Ubiquiti’s website.
3. Step 3: Disable UPnP if enabled. This feature can create security risks.

4.3 Config or Code Example

Before

Username: ubnt, Password: ubnt

After

Username: , Password: 

4.4 Security Practices Relevant to This Vulnerability

Several security practices can help prevent this issue. Least privilege limits the impact of a compromised camera. Strong passwords make brute-force attacks harder. Patch cadence ensures you have the latest security fixes. Network segmentation isolates cameras from critical systems.

• Practice 1: Implement least privilege by restricting network access to only necessary services and ports.
• Practice 2: Enforce strong password policies for all camera accounts.

4.5 Automation (Optional)

Automation is difficult without a central management system. However, you could use scripting tools like Python with the Ubiquiti API to check firmware versions across multiple cameras. This requires prior setup and authentication.

# Example script - requires Ubiquiti API setup
# import ubiquiti
# api = ubiquiti.API()
# for camera in api.cameras:
#   if camera.firmware_version < "latest":
#     print(f"Camera {camera.name} needs firmware update")

5. Verification / Validation

• Post-fix check: Attempt to log in with the default username and password; access should be denied.
• Re-test: Re-run the Nmap scan from step 3.1, confirming no Ubiquiti branding is visible if the camera has been removed or renamed.
• Smoke test: Verify that you can still view the live video stream through the web interface or a surveillance application.
• Monitoring: Check logs for failed login attempts and unusual network activity related to the camera’s IP address.

6. Preventive Measures and Monitoring

• Baselines: Update your network device baseline to require strong passwords and disable default accounts on all IP cameras.
• Asset and patch process: Review camera firmware versions monthly and apply updates promptly.

7. Risks, Side Effects, and Roll Back

Changing credentials could temporarily disrupt access if forgotten. Firmware updates can sometimes cause compatibility issues. A roll back involves restoring the backed-up configuration or reverting to a previous firmware version.

• Risk or side effect 1: Incorrectly configured credentials may lock you out of the camera; keep a record of new passwords.
• Risk or side effect 2: Firmware updates could cause temporary service disruption; schedule during off-peak hours.
• Roll back: Restore the backed-up configuration file through the camera’s web interface, or revert to the previous firmware version if available.
