Comprehensive Technical Analysis of EUVD-2025-4153

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified as EUVD-2025-4153, also known as CVE-2025-26341, is classified under CWE-306, "Missing Authentication for Critical Function." This vulnerability affects the maxprofile/accounts/routes.lua module in Q-Free MaxTime versions up to and including 2.11.0. The severity of this vulnerability is rated with a CVSS Base Score of 9.8, which is considered critical.

The CVSS vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H indicates the following:

• Attack Vector (AV): Network (N) - The vulnerability can be exploited remotely over the network.
• Attack Complexity (AC): Low (L) - The attack requires minimal skill or resources.
• Privileges Required (PR): None (N) - No privileges are required to exploit the vulnerability.
• User Interaction (UI): None (N) - No user interaction is required.
• Scope (S): Unchanged (U) - The vulnerability does not change the security scope.
• Confidentiality (C): High (H) - The vulnerability has a high impact on confidentiality.
• Integrity (I): High (H) - The vulnerability has a high impact on integrity.
• Availability (A): High (H) - The vulnerability has a high impact on availability.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector involves an unauthenticated remote attacker sending crafted HTTP requests to the vulnerable endpoint. The lack of authentication for critical functions allows the attacker to reset arbitrary user passwords. This can be exploited through:

• Automated Scripts: Attackers can use automated scripts to send malicious HTTP requests.
• Manual Exploitation: Knowledgeable attackers can manually craft HTTP requests to exploit the vulnerability.
• Phishing Campaigns: Attackers can use phishing techniques to trick users into visiting malicious sites that send crafted HTTP requests.

3. Affected Systems and Software Versions

The vulnerability affects Q-Free MaxTime software versions up to and including 2.11.0. Organizations using these versions are at risk and should prioritize updating to a patched version.

4. Recommended Mitigation Strategies

To mitigate the risk associated with this vulnerability, the following strategies are recommended:

• Patch Management: Immediately update to a patched version of Q-Free MaxTime.
• Network Segmentation: Isolate critical systems to limit the attack surface.
• Access Controls: Implement strict access controls and authentication mechanisms.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities.
• User Education: Educate users about phishing attacks and the importance of not clicking on suspicious links.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to European organizations using Q-Free MaxTime, particularly those in critical infrastructure sectors such as transportation and logistics. The potential for unauthorized access and data breaches could lead to operational disruptions, financial losses, and reputational damage.

6. Technical Details for Security Professionals

Vulnerability Details:

• Affected Module: maxprofile/accounts/routes.lua
• Vulnerable Function: Password reset functionality
• Exploitation: Crafted HTTP requests can bypass authentication checks, allowing unauthorized password resets.

Detection and Response:

• Intrusion Detection Systems (IDS): Configure IDS to detect unusual HTTP request patterns targeting the vulnerable endpoint.
• Security Information and Event Management (SIEM): Integrate SIEM solutions to correlate and analyze logs for suspicious activities.
• Incident Response Plan: Develop and implement an incident response plan to quickly address any detected exploitation attempts.
