1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-64075 CVSS Score: 10

The CVSS score of 10 indicates that this vulnerability is of critical severity. The path traversal vulnerability in the check_token function of Shenzhen Zhibotong Electronics ZBT WE2001 23.09.27 allows remote attackers to bypass authentication mechanisms. This can lead to unauthorized administrative actions, posing a significant risk to the integrity and confidentiality of the affected systems.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: Attackers can exploit this vulnerability over the network without requiring physical access to the device.
• Session Cookie Manipulation: By crafting a specific session cookie value, attackers can bypass the authentication checks implemented in the check_token function.

Exploitation Methods:

• Path Traversal: Attackers can manipulate the session cookie to traverse directories and access unauthorized files or execute administrative commands.
• Privilege Escalation: Once authenticated, attackers can perform actions typically reserved for administrators, such as modifying system settings, accessing sensitive data, or installing malicious software.

3. Affected Systems and Software Versions

Affected Systems:

• Shenzhen Zhibotong Electronics ZBT WE2001

Affected Software Versions:

• Version 23.09.27

It is crucial to note that other versions of the software may also be affected if they share the same codebase or have similar vulnerabilities.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patch Management: Apply the latest security patches provided by Shenzhen Zhibotong Electronics.
• Network Segmentation: Isolate affected devices from critical network segments to limit potential damage.
• Monitoring: Implement enhanced monitoring for unusual administrative activities and session cookie manipulations.

Long-Term Strategies:

• Code Review: Conduct a thorough code review of the check_token function and related authentication mechanisms.
• Input Validation: Enhance input validation to prevent path traversal and other injection attacks.
• Access Controls: Implement stricter access controls and multi-factor authentication (MFA) for administrative actions.

5. Impact on Cybersecurity Landscape

The discovery of this vulnerability highlights the ongoing challenges in securing IoT devices and embedded systems. The critical severity of this vulnerability underscores the need for robust security practices in the development and maintenance of such devices. Organizations must prioritize security assessments and regular updates to mitigate similar risks in the future.

6. Technical Details for Security Professionals

Vulnerability Details:

• Function Affected: check_token
• Vulnerability Type: Path Traversal
• Exploitation Mechanism: Crafted session cookie value

Detection and Response:

• Log Analysis: Review logs for unusual session cookie values and unauthorized administrative actions.
• Intrusion Detection Systems (IDS): Deploy IDS rules to detect and alert on suspicious session cookie manipulations.
• Incident Response: Develop an incident response plan specific to this vulnerability, including steps for containment, eradication, and recovery.

Example Exploit Code (Hypothetical):

import requests

# Target URL
url = "http://target-device/admin"

# Crafted session cookie value
crafted_cookie = "session=../../../../etc/passwd"

# Set the crafted cookie in the request
cookies = {'session': crafted_cookie}

# Send the request
response = requests.get(url, cookies=cookies)

# Print the response
print(response.text)
