EUVD-2025-10403

Comprehensive Technical Analysis of EUVD-2025-10403

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-10403 pertains to the crud-query-parser library, specifically within the TypeORM adapter. The issue arises from improper neutralization of the order/sort parameter, leading to SQL injection vulnerabilities. This flaw allows an attacker to manipulate SQL queries by injecting malicious code, potentially compromising the integrity and confidentiality of the database.

Severity Evaluation:

• Base Score: 9.3 (Critical)
• Base Score Version: CVSS 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity) and the significant impact on confidentiality and integrity.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network (AV:N): The vulnerability can be exploited remotely over the network.
• Low Complexity (AC:L): The attack does not require specialized conditions or knowledge.

Exploitation Methods:

• SQL Injection: An attacker can craft malicious HTTP requests with specially designed order/sort parameters to inject SQL code. This can lead to unauthorized data access, data manipulation, or even complete database takeover.
• Automated Tools: Attackers may use automated tools to scan for vulnerable endpoints and exploit the SQL injection flaw.

3. Affected Systems and Software Versions

Affected Software:

• Library: crud-query-parser
• Versions: All versions prior to 0.1.0
• Adapter: TypeORM adapter with ordering enabled and without a property filter

Affected Systems:

• Any system or application that uses the crud-query-parser library with the TypeORM adapter and has ordering enabled.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to version 0.1.0 or later of the crud-query-parser library.
• Disable Ordering: Temporarily disable the ordering feature if an immediate upgrade is not possible.
• Property Filter: Implement a property filter to sanitize and validate input parameters.

Long-Term Mitigation:

• Input Validation: Ensure robust input validation and sanitization for all user-supplied data.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability poses a significant risk to organizations within the European Union that rely on the crud-query-parser library. Given the critical nature of the flaw, it could lead to data breaches, financial loss, and reputational damage. The EU's General Data Protection Regulation (GDPR) mandates stringent data protection measures, and organizations must act swiftly to mitigate such vulnerabilities to avoid regulatory penalties.

6. Technical Details for Security Professionals

Vulnerability Details:

• CVE ID: CVE-2025-32020
• Library: crud-query-parser
• Affected Adapter: TypeORM
• Vulnerable Parameter: order/sort
• Exploitation: SQL injection via improper neutralization of the order/sort parameter.

Mitigation Steps:

1. Upgrade the Library: Ensure all systems are updated to crud-query-parser version 0.1.0 or later.
2. Implement Input Validation: Use regular expressions or whitelisting to validate input parameters.
3. Use Parameterized Queries: Replace dynamic SQL queries with parameterized queries to prevent injection attacks.
4. Monitor and Log: Implement monitoring and logging to detect and respond to suspicious activities.
