EUVD-2025-6937

Comprehensive Technical Analysis of EUVD-2025-6937

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-6937 pertains to the mintplex-labs/anything-llm v1.5.11 desktop version for Windows. The application opens server port 3001 on 0.0.0.0 with no authentication by default, allowing unauthorized access to the backend. This vulnerability is critical due to the potential for full backend access, which can lead to actions such as deleting all data from the workspace.

Severity Evaluation:

• Base Score: 9.8
• Base Score Version: 3.0
• Base Score Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector string highlights the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This vulnerability is severe because it can be exploited remotely with low complexity, requiring no privileges or user interaction, and it impacts confidentiality, integrity, and availability significantly.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Access: An attacker can exploit this vulnerability over the network without needing physical access to the system.
• Unauthenticated Access: The lack of authentication on port 3001 allows any attacker to connect and perform actions without needing credentials.

Exploitation Methods:

• Network Scanning: Attackers can scan for open port 3001 on 0.0.0.0 to identify vulnerable systems.
• Backend Access: Once identified, attackers can connect to the port and gain full backend access.
• Data Manipulation: With backend access, attackers can perform various actions, including deleting data, modifying configurations, and potentially injecting malicious code.

3. Affected Systems and Software Versions

Affected Systems:

• Windows desktop systems running mintplex-labs/anything-llm v1.5.11.

Software Versions:

• mintplex-labs/anything-llm v1.5.11
• Potentially other versions <1.6.5, as indicated by the ENISA ID Product.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Firewall Rules: Implement firewall rules to block access to port 3001 from untrusted networks.
• Network Segmentation: Segregate the vulnerable application from critical systems to limit potential damage.

Long-Term Mitigation:

• Update Software: Upgrade to a patched version of mintplex-labs/anything-llm (version 1.6.5 or later).
• Authentication: Ensure that any open ports require authentication and are configured securely.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.

5. Impact on European Cybersecurity Landscape

This vulnerability poses a significant risk to organizations and individuals using the affected software within the European Union. The potential for unauthorized access and data manipulation can lead to data breaches, financial loss, and reputational damage. Given the critical nature of the vulnerability, it underscores the importance of robust cybersecurity practices and timely patch management.

6. Technical Details for Security Professionals

Detection:
