CVE-2025-26361

Comprehensive Technical Analysis of CVE-2025-26361

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-26361 CISA Vulnerability Name: CVE-2025-26361 Description: The vulnerability is classified as CWE-306, "Missing Authentication for Critical Function." Specifically, the maxprofile/setup/routes.lua file in Q-Free MaxTime versions up to and including 2.11.0 lacks proper authentication mechanisms, allowing unauthenticated remote attackers to factory reset the device via crafted HTTP requests. CVSS Score: 9.1

Severity Evaluation:

• CVSS Base Score: 9.1 (Critical)
• Impact Metrics:
  • Confidentiality: None
  • Integrity: High
  • Availability: High
• Exploitability Metrics:
  • Attack Vector: Network
  • Attack Complexity: Low
  • Privileges Required: None
  • User Interaction: None
  • Scope: Unchanged

The high CVSS score indicates a critical vulnerability that can be easily exploited with severe consequences, particularly affecting the integrity and availability of the device.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated HTTP Requests: An attacker can send specially crafted HTTP requests to the vulnerable endpoint without needing any authentication.
• Network Access: The attacker needs network access to the device, which could be achieved through various means such as compromising the local network, exploiting other vulnerabilities, or gaining access through exposed services.

Exploitation Methods:

• Crafted HTTP Requests: The attacker can send HTTP requests to the maxprofile/setup/routes.lua endpoint with specific parameters to trigger a factory reset.
• Automated Scripts: Attackers can use automated scripts to scan for vulnerable devices and send the necessary HTTP requests to exploit the vulnerability.

3. Affected Systems and Software Versions

Affected Systems:

• Q-Free MaxTime devices running versions up to and including 2.11.0.

Software Versions:

• All versions of Q-Free MaxTime less than or equal to 2.11.0.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Network Segmentation: Isolate the affected devices from public networks and restrict access to trusted networks only.
• Firewall Rules: Implement firewall rules to block unauthorized access to the maxprofile/setup/routes.lua endpoint.
• Monitoring: Increase monitoring and logging of network traffic to detect and respond to suspicious activities.

Long-Term Mitigation:

• Patch Management: Apply the vendor-provided patch or upgrade to a version higher than 2.11.0 as soon as it becomes available.
• Authentication Enforcement: Ensure that all critical functions require proper authentication and authorization.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on Cybersecurity Landscape

Immediate Impact:

• Device Integrity: Unauthenticated factory resets can lead to loss of configuration settings, data, and potential service disruptions.
• Operational Disruption: Affected organizations may experience significant operational disruptions, leading to financial losses and reputational damage.

Long-Term Impact:

• Increased Awareness: This vulnerability highlights the importance of robust authentication mechanisms for critical functions, prompting vendors to prioritize security in their development processes.
• Regulatory Compliance: Organizations may face regulatory scrutiny and potential penalties for non-compliance with security standards and best practices.

6. Technical Details for Security Professionals

Vulnerability Details:

• Affected File: maxprofile/setup/routes.lua
• Vulnerable Function: The specific function within the file that handles factory reset operations lacks authentication checks.
• Exploit Payload: Crafted HTTP requests targeting the vulnerable endpoint with parameters designed to trigger a factory reset.

Detection and Response:

• Intrusion Detection Systems (IDS): Configure IDS to detect and alert on suspicious HTTP requests targeting the maxprofile/setup/routes.lua endpoint.
• Log Analysis: Analyze web server logs for unusual patterns or repeated requests to the vulnerable endpoint.
• Incident Response: Develop and implement an incident response plan to quickly identify, contain, and remediate any exploitation attempts.

Conclusion: CVE-2025-26361 represents a critical vulnerability that underscores the importance of robust authentication mechanisms for critical functions. Organizations using Q-Free MaxTime devices should prioritize immediate mitigation strategies and plan for long-term security enhancements to protect against similar threats.
