EUVD-2025-20288

Comprehensive Technical Analysis of EUVD-2025-20288

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the WeGIA web manager for charitable institutions is an SQL Injection (SQLi) flaw in the /html/funcionario/profile_funcionario.php endpoint. Specifically, the id_funcionario parameter is not properly sanitized or validated before being used in a SQL query. This allows an unauthenticated attacker to inject arbitrary SQL commands, potentially leading to unauthorized access, data manipulation, or data exfiltration.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The high base score indicates a critical vulnerability due to the following factors:

• Attack Vector (AV:N): Network-based attack, which means it can be exploited remotely.
• Attack Complexity (AC:L): Low complexity, indicating that the attack does not require specialized conditions.
• Privileges Required (PR:N): No privileges are required, meaning an unauthenticated attacker can exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required.
• Scope (S:U): Unchanged, meaning the vulnerability affects the same security scope.
• Confidentiality (C:H), Integrity (I:H), Availability (A:H): High impact on all three CIA triad components.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated SQL Injection: An attacker can craft a malicious SQL query by manipulating the id_funcionario parameter in the URL.
• Automated Scanning: Attackers can use automated tools to scan for vulnerable endpoints and exploit them.

Exploitation Methods:

• Data Exfiltration: Injecting SQL commands to extract sensitive data from the database.
• Data Manipulation: Modifying database entries to disrupt operations or insert malicious data.
• Privilege Escalation: Executing SQL commands to gain higher privileges within the database.

3. Affected Systems and Software Versions

Affected Systems:

• WeGIA web manager for charitable institutions.

Affected Software Versions:

• All versions prior to 3.4.3.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade: Upgrade to WeGIA version 3.4.3 or later, which includes the fix for this vulnerability.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially those used in SQL queries.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection.
• Web Application Firewall (WAF): Deploy a WAF to detect and block SQL injection attempts.

Long-Term Mitigation:

• Security Training: Conduct regular security training for developers to understand and mitigate SQL injection vulnerabilities.
• Code Review: Implement a robust code review process to identify and fix security issues early in the development cycle.
• Regular Audits: Perform regular security audits and penetration testing to identify and address vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, a tool used by charitable institutions, poses a significant risk to the European cybersecurity landscape. Charitable institutions often handle sensitive data, including personal information of donors and beneficiaries. An exploit of this vulnerability could lead to data breaches, financial losses, and reputational damage for these institutions.

Given the critical nature of the vulnerability and its potential impact, it is essential for organizations using WeGIA to prioritize patching and implementing robust security measures to protect against SQL injection attacks.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /html/funcionario/profile_funcionario.php
• Parameter: id_funcionario
• Vulnerability Type: SQL Injection
• Exploitability: Unauthenticated, remote exploitation

References:

• GitHub Advisory: GHSA-rrj6-pj6w-8j2r
• Fix Commit: 0a061bcc5024937edd18ab3e65ccc8f38deb6957

Mitigation Steps:

1. Upgrade to Version 3.4.3: Ensure all instances of WeGIA are updated to the latest version.
2. Input Sanitization: Implement input sanitization for all user inputs.
3. Parameterized Queries: Use parameterized queries to prevent SQL injection.
4. WAF Deployment: Deploy a WAF to monitor and block malicious SQL injection attempts.

By addressing this vulnerability promptly and comprehensively, organizations can significantly reduce the risk of SQL injection attacks and protect their sensitive data.
