EUVD-2025-21769

Comprehensive Technical Analysis of EUVD-2025-21769

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-21769 pertains to a SQL Injection flaw in the WeGIA web manager, specifically affecting versions prior to 3.4.6. The vulnerability is located in the idatendido_familiares parameter of the /html/funcionario/dependente_editarInfoPessoal.php endpoint. This vulnerability allows an attacker to manipulate SQL queries, potentially leading to unauthorized access to sensitive database information, including table names and data.

Severity Evaluation:

• Base Score: 9.4 (CVSS: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 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:L): Low privileges are required, meaning that even users with minimal access can exploit the vulnerability.
• User Interaction (UI:N): No user interaction is required for the attack to succeed.
• Confidentiality (VC:H), Integrity (VI:H), and Availability (VA:H): High impact on all three aspects, indicating severe potential damage.
• Scope Change (SC:H), Scope Integrity (SI:H), and Scope Availability (SA:H): High impact on the scope, indicating that the vulnerability can affect components beyond its initial scope.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• SQL Injection: An attacker can inject malicious SQL code into the idatendido_familiares parameter to manipulate the database queries.
• Remote Exploitation: Given the network-based attack vector, the vulnerability can be exploited remotely without requiring physical access to the system.

Exploitation Methods:

• Manipulating SQL Queries: By crafting specific SQL commands, an attacker can extract sensitive information, modify database entries, or even delete data.
• 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 versions prior to 3.4.6.

Software Versions:

• All versions of WeGIA before 3.4.6 are vulnerable.

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: Upgrade to WeGIA version 3.4.6 or later, which includes the fix for this vulnerability.
• Patch Management: Ensure that all systems running WeGIA are regularly updated and patched.

Long-Term Strategies:

• Input Validation: Implement robust input validation and sanitization to prevent SQL Injection attacks.
• Parameterized Queries: Use parameterized queries or prepared statements to ensure that SQL commands are executed safely.
• Web Application Firewalls (WAF): Deploy WAFs to detect and block malicious SQL Injection attempts.
• Regular Audits: Conduct regular security audits and vulnerability assessments to identify and mitigate potential threats.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, which is focused on the Portuguese language and charitable institutions, highlights the importance of securing open-source software used by non-profit organizations. Given the critical nature of the data handled by such institutions, a breach could have severe consequences, including data theft, financial loss, and reputational damage. This underscores the need for continuous monitoring and timely patching of open-source software to protect sensitive information and maintain public trust.
