EUVD-2025-25464

Comprehensive Technical Analysis of EUVD-2025-25464

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in EUVD-2025-25464 pertains to a SQL Injection flaw in the WeGIA Web manager, specifically affecting versions prior to 3.4.10. The vulnerability resides in the /html/funcionario/dependente_remover.php endpoint, particularly in the id_funcionario parameter. This vulnerability allows attackers to execute arbitrary SQL commands, thereby compromising the confidentiality, integrity, and availability of the database.

Severity Evaluation:

• Base Score: 9.4 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

The high base score indicates a critical vulnerability due to the potential for significant impact on the database and the ease of exploitation. The attack vector (AV:N) is network-based, requiring low attack complexity (AC:L) and no user interaction (UI:N). The attacker needs low privileges (PR:L) to exploit the vulnerability, and the impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Network-Based Attack: The attacker can exploit the vulnerability remotely over the network.
• Low Privilege Requirement: The attacker needs only low-level privileges to exploit the vulnerability.

Exploitation Methods:

• SQL Injection: The attacker can inject malicious SQL code into the id_funcionario parameter to manipulate the database. This can result in unauthorized access to data, data modification, or even data deletion.
• Automated Tools: Attackers may use automated tools to scan for and exploit SQL Injection vulnerabilities, making the attack more efficient and widespread.

3. Affected Systems and Software Versions

Affected Systems:

• WeGIA Web Manager: All versions prior to 3.4.10 are affected.

Software Versions:

• WeGIA < 3.4.10: The vulnerability is present in all versions of WeGIA before 3.4.10.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Upgrade to Version 3.4.10: Users should immediately upgrade to WeGIA version 3.4.10 or later, where the vulnerability has been fixed.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for parameters like id_funcionario.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL Injection attacks.

Long-Term Mitigation:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block malicious traffic targeting SQL Injection vulnerabilities.
• Security Training: Provide security training for developers to ensure they are aware of common vulnerabilities and best practices for secure coding.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, a Web manager 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. A successful exploitation of this vulnerability could lead to data breaches, financial loss, 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 take immediate action to mitigate the risk. The European Union's focus on data protection and privacy, as outlined in regulations like GDPR, underscores the importance of addressing such vulnerabilities promptly.
