CVE-2025-27214

Comprehensive Technical Analysis of CVE-2025-27214

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-27214 CISA Vulnerability Name: CVE-2025-27214 Description: A Missing Authentication for Critical Function vulnerability in the UniFi Connect EV Station Pro may allow a malicious actor with physical or adjacent access to perform an unauthorized factory reset.

Severity Evaluation:

• CVSS Score: 9.8
• Severity: Critical

The high CVSS score of 9.8 indicates a severe vulnerability. The critical function of factory reset, when unauthorized, can lead to significant disruptions and potential security breaches.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

1. Physical Access: An attacker with physical access to the UniFi Connect EV Station Pro can exploit the vulnerability by directly interacting with the device.
2. Adjacent Access: An attacker within close proximity, such as on the same local network, could potentially exploit the vulnerability through network-based attacks.

Exploitation Methods:

1. Direct Interaction: An attacker could use the device's interface or physical buttons to trigger the factory reset without authentication.
2. Network Commands: If the device is network-accessible, an attacker could send unauthenticated commands to initiate the factory reset.

3. Affected Systems and Software Versions

Affected Products:

• UniFi Connect EV Station Pro (Version 1.5.18 and earlier)

Affected Versions:

• All versions up to and including 1.5.18

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update Firmware: Upgrade the UniFi Connect EV Station Pro to Version 1.5.27 or later. This update includes patches that address the missing authentication vulnerability.

Additional Mitigation Strategies:

1. Physical Security: Ensure that the UniFi Connect EV Station Pro is located in a secure area with restricted physical access.
2. Network Segmentation: Isolate the device on a separate network segment to limit adjacent access.
3. Monitoring: Implement continuous monitoring and logging to detect any unauthorized access attempts.
4. Access Controls: Enforce strict access controls and authentication mechanisms for any critical functions.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Service Disruption: Unauthorized factory resets can lead to significant service disruptions, affecting the availability and reliability of EV charging stations.
• Data Loss: A factory reset may result in the loss of configuration data and user settings, requiring manual reconfiguration.

Long-Term Impact:

• Reputation Damage: Frequent exploitation of such vulnerabilities can damage the reputation of the vendor and the trust in their products.
• Increased Attack Surface: If not addressed promptly, similar vulnerabilities could be discovered in other IoT devices, increasing the overall attack surface.

6. Technical Details for Security Professionals

Vulnerability Details:

• Type: Missing Authentication for Critical Function
• Impact: Unauthorized factory reset
• Exploitation: Requires physical or adjacent access

Technical Recommendations:

1. Code Review: Conduct a thorough code review to ensure that all critical functions require proper authentication.
2. Penetration Testing: Perform regular penetration testing to identify and mitigate similar vulnerabilities.
3. Security Audits: Implement regular security audits to assess the security posture of IoT devices and their firmware.
