EUVD-2025-2660

Comprehensive Technical Analysis of EUVD-2025-2660

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-2660 pertains to a SQL Injection flaw in the WeGIA web manager, specifically affecting the /dao/verificar_recursos_cargo.php endpoint via the cargo parameter. This vulnerability allows attackers to execute arbitrary SQL commands, which can compromise the confidentiality, integrity, and availability of the database.

Severity Evaluation:

• Base Score: 9.4 (CVSS 4.0)
• Vector String: 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 complexity (AC:L) and no user interaction (UI:N). The attacker needs low privileges (PR:L) to exploit this 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 vulnerability can be exploited remotely over the network.
• Low Complexity: The attack requires minimal effort and can be executed with standard SQL injection techniques.

Exploitation Methods:

• SQL Injection: An attacker can inject malicious SQL code into the cargo parameter to manipulate the database. This can include extracting sensitive data, modifying database entries, or deleting records.
• 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 3.2.8 are vulnerable.

Software Versions:

• All versions of WeGIA before 3.2.8 are affected. Users should upgrade to version 3.2.8 or later to mitigate the risk.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to WeGIA version 3.2.8 or later, which includes the fix for this vulnerability.
• Input Validation: Implement strict input validation and sanitization for all user inputs, especially for parameters like cargo.
• Parameterized Queries: Use parameterized queries or prepared statements to prevent SQL injection attacks.

Long-Term Strategies:

• Regular Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
• Web Application Firewalls (WAF): Deploy WAFs to monitor and block malicious SQL injection attempts.
• Security Training: Provide training for developers on secure coding practices to prevent future SQL injection vulnerabilities.

5. Impact on European Cybersecurity Landscape

The presence of such a critical vulnerability in a web manager used by charitable institutions highlights the importance of robust cybersecurity measures in the non-profit sector. Given the sensitive nature of data handled by these organizations, a breach could have severe consequences, including financial loss, reputational damage, and legal repercussions.

Regulatory Compliance:

• GDPR: Organizations must ensure compliance with GDPR, which mandates strong data protection measures. Failure to address such vulnerabilities could result in significant fines and penalties.
• NIS Directive: For critical infrastructure, compliance with the NIS Directive is essential to maintain the security and resilience of networks and information systems.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: /dao/verificar_recursos_cargo.php
• Parameter: cargo
• Vulnerability Type: SQL Injection

Exploitation Example: An attacker could inject SQL code into the cargo parameter, such as:

cargo=1'; DROP TABLE users; --

This would result in the execution of the DROP TABLE users command, deleting the users table from the database.

Mitigation Code Example: To mitigate this vulnerability, use parameterized queries:

$stmt = $pdo->prepare("SELECT * FROM resources WHERE cargo = :cargo");
$stmt->execute(['cargo' => $cargo]);
