EUVD-2025-0106

Comprehensive Technical Analysis of EUVD-2025-0106

1. Vulnerability Assessment and Severity Evaluation

Vulnerability Description: The vulnerability in Mongoose before version 8.9.5 allows for improper use of a nested $where filter with a populate() match, leading to search injection. This issue is a result of an incomplete fix for CVE-2024-53900.

Severity Evaluation: The vulnerability has a CVSS Base Score of 9.0, which is considered critical. The CVSS vector CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H indicates the following:

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

This high severity score underscores the potential for significant impact if exploited, including unauthorized access to sensitive data, data manipulation, and service disruption.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attacks: Given the network attack vector, an attacker can exploit this vulnerability remotely without needing local access.
• Search Injection: The primary exploitation method involves injecting malicious search queries through the $where filter and populate() match, which can lead to unauthorized data access and manipulation.

Exploitation Methods:

• Crafted Queries: An attacker can craft specific queries that exploit the nested $where filter to bypass intended search constraints.
• Automated Tools: Attackers may use automated tools to scan for vulnerable Mongoose instances and execute search injection attacks.

3. Affected Systems and Software Versions

Affected Versions:

• Mongoose versions before 6.13.6
• Mongoose versions before 7.8.4
• Mongoose versions before 8.9.5

Affected Systems:

• Any system or application using the vulnerable versions of Mongoose, particularly those that rely on MongoDB for data storage and retrieval.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade Mongoose: Upgrade to Mongoose version 8.9.5 or later to mitigate the vulnerability.
• Patch Management: Ensure that all systems using Mongoose are regularly updated and patched.

Long-Term Strategies:

• Input Validation: Implement robust input validation to prevent malicious queries from being processed.
• Access Controls: Enforce strict access controls and authentication mechanisms to limit unauthorized access.
• Monitoring and Logging: Enhance monitoring and logging to detect and respond to suspicious activities related to search queries.

5. Impact on European Cybersecurity Landscape

Regulatory Compliance:

• GDPR: Organizations must ensure that personal data is protected, and any breach due to this vulnerability could result in significant fines and reputational damage.
• NIS Directive: Critical infrastructure providers must adhere to stringent security measures, and failure to address this vulnerability could lead to regulatory penalties.

Economic Impact:

• Data Breaches: Potential data breaches could result in financial losses, legal liabilities, and loss of customer trust.
• Operational Disruption: Exploitation of this vulnerability could lead to service disruptions, affecting business continuity.

6. Technical Details for Security Professionals

Technical Overview:

• Vulnerability Type: Search Injection
• Root Cause: Incomplete fix for CVE-2024-53900, allowing improper use of nested $where filters.
• Exploitation: Attackers can inject malicious search queries to bypass intended constraints, leading to unauthorized data access and manipulation.

Mitigation Steps:

1. Upgrade Mongoose: Ensure all instances are upgraded to version 8.9.5 or later.
2. Input Sanitization: Implement strict input sanitization to prevent injection attacks.
3. Access Controls: Enforce least privilege access controls and regular audits.
4. Monitoring: Deploy intrusion detection systems (IDS) and intrusion prevention systems (IPS) to monitor for suspicious activities.
5. Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate similar issues.
