CVE-2025-26347

Comprehensive Technical Analysis of CVE-2025-26347

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-26347 CISA Vulnerability Name: CVE-2025-26347 CVSS Score: 9.8

The vulnerability identified as CVE-2025-26347 is classified under CWE-306, "Missing Authentication for Critical Function." This type of vulnerability occurs when a critical function does not properly authenticate users, allowing unauthorized access to sensitive operations. The CVSS score of 9.8 indicates a critical severity level, highlighting the significant risk posed by this vulnerability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Remote Access: An attacker can exploit this vulnerability by sending crafted HTTP requests to the affected endpoint (maxprofile/menu/routes.lua) without needing any authentication.
• Permission Manipulation: The attacker can edit user permissions, potentially escalating privileges or revoking access for legitimate users.

Exploitation Methods:

• Crafted HTTP Requests: The attacker can use tools like curl, Postman, or custom scripts to send HTTP requests designed to modify user permissions.
• Automated Scripts: Attackers may develop automated scripts to exploit this vulnerability en masse, targeting multiple instances of the affected software.

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 the maxprofile/menu/routes.lua endpoint exposed to the internet or internal networks.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Network Segmentation: Isolate the affected systems from public networks to limit exposure.
• Firewall Rules: Implement strict firewall rules to block unauthorized access to the maxprofile/menu/routes.lua endpoint.
• Monitoring: Enhance monitoring and logging for suspicious activities related to the vulnerable endpoint.

Long-Term Mitigation:

• Patch Management: Upgrade to a patched version of Q-Free MaxTime as soon as it becomes available.
• Authentication Enforcement: Ensure that all critical functions require proper authentication and authorization.
• Regular Audits: Conduct regular security audits to identify and mitigate similar vulnerabilities.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-26347 underscores the importance of robust authentication mechanisms in software design. This vulnerability can lead to significant security breaches, including unauthorized access, data manipulation, and privilege escalation. Organizations must prioritize patching and implementing strong authentication controls to mitigate such risks.

6. Technical Details for Security Professionals

Vulnerability Details:

• Location: The vulnerability resides in the maxprofile/menu/routes.lua file within the Q-Free MaxTime software.
• Cause: The critical function responsible for editing user permissions does not enforce authentication, allowing unauthenticated users to perform these actions.

Detection and Response:

• Detection: Implement intrusion detection systems (IDS) and intrusion prevention systems (IPS) to detect and block suspicious HTTP requests targeting the vulnerable endpoint.
• Response: Develop incident response plans to quickly identify and mitigate any exploitation attempts. Ensure that logs are reviewed regularly for any unauthorized access attempts.

Code Review:

• Authentication Checks: Ensure that all critical functions include proper authentication checks. Use frameworks and libraries that enforce secure coding practices.
• Input Validation: Validate all inputs to prevent crafted requests from bypassing security controls.

Conclusion: CVE-2025-26347 represents a critical vulnerability that can be exploited to gain unauthorized access to user permissions. Organizations using Q-Free MaxTime versions less than or equal to 2.11.0 should prioritize upgrading to a patched version and implementing robust authentication mechanisms to mitigate this risk. Regular security audits and proactive monitoring are essential to maintain a strong security posture.
