CVE-2025-24285

Comprehensive Technical Analysis of CVE-2025-24285

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24285 CISA Vulnerability Name: CVE-2025-24285 Description: Multiple Improper Input Validation vulnerabilities in UniFi Connect EV Station Lite may allow a Command Injection by a malicious actor with network access to the UniFi Connect EV Station Lite.

Severity Evaluation:

• CVSS Score: 9.8
• Severity: Critical

The high CVSS score of 9.8 indicates that this vulnerability poses a significant risk. The critical nature of the vulnerability is due to the potential for command injection, which can lead to arbitrary code execution and complete system compromise.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network Access: The vulnerability requires network access to the UniFi Connect EV Station Lite. This could be achieved through local network access or remote access if the device is exposed to the internet.
• Improper Input Validation: The core issue is improper input validation, which allows an attacker to inject malicious commands.

Exploitation Methods:

• Command Injection: An attacker can craft specially designed input to inject commands that the system will execute. This can include commands to download and execute malware, exfiltrate data, or manipulate the device's functionality.
• Remote Code Execution (RCE): By exploiting the command injection vulnerability, an attacker can achieve remote code execution, leading to full control over the device.

3. Affected Systems and Software Versions

Affected Products:

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

Software Versions:

• All versions up to and including 1.5.1 are vulnerable.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Update Software: Upgrade the UniFi Connect EV Station Lite to Version 1.5.2 or later. This update includes patches that address the improper input validation issues.

Additional Mitigation Strategies:

• 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.
• Input Validation: Ensure that all input is properly validated and sanitized to prevent command injection.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on Cybersecurity Landscape

Broader Implications:

• IoT Security: This vulnerability highlights the ongoing challenges in securing Internet of Things (IoT) devices. Improper input validation is a common issue in IoT devices, which often lack robust security measures.
• Supply Chain Risks: Vulnerabilities in IoT devices can have cascading effects on supply chains and critical infrastructure, especially in sectors like energy and transportation.
• Regulatory Compliance: Organizations must ensure compliance with regulatory standards and best practices to mitigate such vulnerabilities.

6. Technical Details for Security Professionals

Technical Analysis:

• Input Validation Flaws: The vulnerability stems from inadequate input validation mechanisms, which fail to sanitize user input properly. This allows an attacker to inject commands that the system will execute.
• Command Injection: The command injection vulnerability can be exploited by sending specially crafted input that includes system commands. For example, an attacker might inject commands to create a reverse shell or execute arbitrary code.
• Network Access: The attacker needs network access to the device, which can be achieved through local network access or remote access if the device is exposed to the internet.

Detection and Response:

• Intrusion Detection Systems (IDS): Deploy IDS to monitor for suspicious network activity and command injection attempts.
• Log Analysis: Regularly review logs for unusual commands or activities that may indicate an exploitation attempt.
• Incident Response: Have an incident response plan in place to quickly address and mitigate any successful exploitation attempts.

Conclusion: CVE-2025-24285 is a critical vulnerability that underscores the importance of robust input validation and regular software updates in IoT devices. Organizations should prioritize updating affected devices and implementing additional security measures to mitigate the risk of command injection attacks.
