CVE-2025-26359

Comprehensive Technical Analysis of CVE-2025-26359

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-26359 CISA Vulnerability Name: CVE-2025-26359 Description: The vulnerability is classified as CWE-306 "Missing Authentication for Critical Function" in the maxprofile/accounts/routes.lua file of Q-Free MaxTime versions less than or equal to 2.11.0. This flaw allows an unauthenticated remote attacker to reset user PINs via crafted HTTP requests. CVSS Score: 9.8

Severity Evaluation:

• CVSS Base Score: 9.8 (Critical)
• Impact: The vulnerability can lead to unauthorized access and potential compromise of user accounts, resulting in significant security risks.
• Exploitability: The ease of exploitation is high due to the lack of authentication for critical functions, making it a prime target for attackers.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated HTTP Requests: An attacker can send specially crafted HTTP requests to the vulnerable endpoint to reset user PINs without needing any authentication.
• Automated Scripts: Attackers can use automated scripts to exploit this vulnerability en masse, targeting multiple user accounts simultaneously.

Exploitation Methods:

• Crafted HTTP Requests: By analyzing the routes.lua file, an attacker can identify the specific HTTP request format required to reset user PINs.
• Brute Force Attacks: Once PINs are reset, attackers can attempt brute force attacks to gain unauthorized access to user accounts.

3. Affected Systems and Software Versions

Affected Software:

• Q-Free MaxTime: Versions less than or equal to 2.11.0

Affected Systems:

• Any system running the vulnerable versions of Q-Free MaxTime, particularly those with exposed endpoints accessible over the internet.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to a patched version of Q-Free MaxTime that addresses this vulnerability.
• Access Controls: Implement strict access controls to limit exposure of the vulnerable endpoint.
• Network Segmentation: Segment the network to isolate critical systems and reduce the attack surface.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and vulnerability assessments.
• Authentication Mechanisms: Ensure that all critical functions require proper authentication.
• Monitoring: Implement continuous monitoring to detect and respond to suspicious activities.

5. Impact on Cybersecurity Landscape

Broader Implications:

• User Trust: Compromise of user PINs can lead to a loss of trust in the service provider.
• Data Integrity: Unauthorized access can result in data breaches and integrity issues.
• Regulatory Compliance: Organizations may face regulatory penalties for failing to protect user data.

Industry Trends:

• Increased Awareness: This vulnerability highlights the importance of robust authentication mechanisms for critical functions.
• Best Practices: Encourages the adoption of best practices in software development and security testing.

6. Technical Details for Security Professionals

Vulnerability Details:

• File Affected: maxprofile/accounts/routes.lua
• Vulnerable Function: The specific function within routes.lua that handles PIN reset requests without proper authentication.

Exploitation Steps:

1. Identify Vulnerable Endpoint: Use tools like curl or Burp Suite to identify the vulnerable endpoint.
2. Craft HTTP Request: Create an HTTP request that mimics the legitimate PIN reset request but without authentication.
3. Send Request: Send the crafted request to the vulnerable endpoint to reset the user PIN.

Detection and Response:

• Log Analysis: Monitor logs for unusual PIN reset activities.
• Intrusion Detection Systems (IDS): Deploy IDS to detect and alert on suspicious HTTP requests.
• Incident Response Plan: Develop and implement an incident response plan to quickly address any detected exploitation attempts.

Conclusion: CVE-2025-26359 represents a critical vulnerability that requires immediate attention. Organizations using Q-Free MaxTime should prioritize patching and implementing robust security measures to mitigate the risk. This vulnerability underscores the importance of thorough security testing and the implementation of strong authentication mechanisms for critical functions.
