EUVD-2025-25502

Comprehensive Technical Analysis of EUVD-2025-25502

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-25502 pertains to multiple improper input validation issues in the UniFi Connect EV Station Lite. These vulnerabilities can lead to command injection attacks, allowing a malicious actor with network access to execute arbitrary commands on the affected device.

Severity Evaluation:

• CVSS Base Score: 9.8
• CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector breakdown shows that the attack can be executed over the network (AV:N), requires low complexity (AC:L), does not need any privileges (PR:N) or user interaction (UI:N), and has a high impact on confidentiality, integrity, and availability (C:H/I:H/A:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network Access: The attacker needs network access to the UniFi Connect EV Station Lite. This could be achieved through local network access or remotely if the device is exposed to the internet.
• Command Injection: The attacker can exploit the improper input validation to inject malicious commands, potentially leading to unauthorized access, data manipulation, or denial of service.

Exploitation Methods:

• Crafted Inputs: The attacker can send specially crafted inputs to the device, exploiting the lack of proper validation to execute arbitrary commands.
• Automated Tools: Attackers may use automated tools to scan for vulnerable devices and exploit them en masse.

3. Affected Systems and Software Versions

Affected Products:

• UniFi Connect EV Station Lite (Version 1.5.1 and earlier)

Vendor:

• Ubiquiti Inc.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update Software: Upgrade the UniFi Connect EV Station Lite to Version 1.5.2 or later, which includes patches for the vulnerabilities.

Additional Mitigation:

• Network Segmentation: Isolate the UniFi Connect EV Station Lite on a separate network segment to limit exposure.
• Firewall Rules: Implement strict firewall rules to restrict access to the device.
• Monitoring: Enable logging and monitoring to detect any suspicious activity.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to the European cybersecurity landscape, particularly in sectors relying on electric vehicle (EV) charging infrastructure. Unauthorized access to EV charging stations can lead to:

• Service Disruption: Attackers could disrupt charging services, affecting EV users.
• Data Breach: Sensitive data, such as user information and charging logs, could be compromised.
• Safety Risks: Manipulation of charging parameters could pose physical safety risks.

6. Technical Details for Security Professionals

Vulnerability Details:

• Improper Input Validation: The device fails to properly validate user inputs, allowing for command injection.
• Command Injection: The attacker can inject commands through unvalidated inputs, leading to arbitrary command execution.

Detection and Response:

• Intrusion Detection Systems (IDS): Deploy IDS to detect unusual network traffic patterns indicative of command injection attempts.
• Log Analysis: Regularly review logs for any signs of unauthorized access or command execution.
• Incident Response Plan: Develop and maintain an incident response plan tailored to handle command injection attacks on EV charging infrastructure.
