How to remediate – AXIS Camera Unsecured Feed Detection

1. Introduction

The AXIS Camera Unsecured Feed Detection vulnerability refers to instances where an Axis Network Camera feed is accessible remotely without requiring authentication. This poses a risk of unauthorized access to sensitive video data, potentially impacting confidentiality and allowing attackers to view live or recorded footage. These cameras are commonly found in businesses, public spaces, and residential settings. A successful exploit could lead to information disclosure.

2. Technical Explanation

The vulnerability occurs when the camera’s web interface is not properly secured, often due to default credentials, misconfigured access controls, or lack of authentication requirements on the live feed itself. An attacker can directly connect to the camera’s IP address and port using a standard web browser or video player without being prompted for login details. There are no known CVEs associated with this specific detection but it is related to weak configuration practices. For example, an attacker could discover the camera’s IP address through network scanning and then access the feed directly in their browser.

• Root cause: Missing or weak authentication on the camera’s live video stream.
• Exploit mechanism: An attacker connects to the camera’s public IP address and port (typically 80 or 443) via HTTP/HTTPS, bypassing any login requirements for viewing the feed.
• Scope: Axis Network Cameras with publicly accessible feeds are affected. Specific models and firmware versions may be more vulnerable depending on default configurations.

3. Detection and Assessment

Confirming vulnerability involves checking if a camera’s live feed is accessible without credentials. A quick check can be performed using a web browser, while thorough assessment requires network scanning.

• Quick checks: Open a web browser and navigate to the camera’s IP address (e.g., http://) or HTTPS equivalent. If the live feed displays without prompting for credentials, the camera is likely vulnerable.
• Scanning: Nessus vulnerability scan ID 16289 can identify unsecured Axis camera feeds. This should be used as an example only.
• Logs and evidence: Camera logs may show connections from unauthorized IP addresses accessing the feed directly. Check for successful access attempts without corresponding authentication events.

curl -I http://<camera_ip_address> #Check HTTP headers for authentication requirements

4. Solution / Remediation Steps

Securing the camera feed requires following vendor recommendations, including strong password configuration and access control adjustments.

4.1 Preparation

• No services need to be stopped for this remediation.

4.2 Implementation

1. Step 1: Change the default administrator password to a strong, unique value.
2. Step 2: Enable authentication for accessing the live video feed. This is typically found in the camera’s web interface under security settings.
3. Step 3: Restrict access to authorized IP addresses or networks only.

4.3 Config or Code Example

Before

# Default configuration, no authentication required for live feed access

After

# Authentication enabled for live feed access with strong password and IP restrictions.  (Configuration steps vary by camera model - consult vendor documentation)

4.4 Security Practices Relevant to This Vulnerability

Practices that directly address this vulnerability type include least privilege, secure defaults, and patch cadence.

• Practice 1: Least privilege – restrict access to the camera’s web interface and feed only to authorized personnel.
• Practice 2: Secure defaults – change default credentials immediately upon deployment.

4.5 Automation (Optional)

Automation is not typically suitable for this vulnerability due to the need for specific configuration changes within each camera’s web interface.

5. Verification / Validation

Confirming the fix involves verifying that authentication is now required to access the live feed and that unauthorized access is blocked.

• Re-test: Re-run the quick check from Section 3. Access should now be denied without valid credentials.
• Smoke test: Verify that authorized users can still access the live feed with their new credentials.
• Monitoring: Check camera logs for failed login attempts from unauthorized IP addresses.

curl -I http://<camera_ip_address> #Check HTTP headers should now show authentication required

6. Preventive Measures and Monitoring

Preventive measures include updating security baselines, implementing a patch cadence, and regularly reviewing camera configurations.

• Baselines: Update a security baseline to require strong passwords and authentication for all network cameras.
• Pipelines: Implement configuration checks during deployment to ensure default credentials are changed and basic security settings are applied.
• Asset and patch process: Review camera configurations regularly (e.g., quarterly) to identify any misconfigurations or vulnerabilities.

7. Risks, Side Effects, and Roll Back

Potential risks include service disruption if incorrect configuration changes are made. Roll back involves restoring the backed-up configuration file.

• Risk or side effect 1: Incorrect configuration may prevent authorized users from accessing the camera feed.
• Risk or side effect 2: Changes to network settings could temporarily disrupt connectivity.
• Roll back: Restore the previously backed-up configuration file through the camera’s web interface.
