EUVD-2025-3987

Comprehensive Technical Analysis of EUVD-2025-3987

1. Vulnerability Assessment and Severity Evaluation

The vulnerability EUVD-2025-3987 pertains to a SQL Injection flaw in the WeGIA application, specifically within the get_detalhes_cobranca.php endpoint. This vulnerability allows an authorized attacker to execute arbitrary SQL queries, potentially leading to unauthorized access, modification, or deletion of sensitive information.

Severity Evaluation:

• Base Score: 10.0 (Critical)
• Base Score Version: 4.0
• Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H

The CVSS score of 10.0 indicates a critical vulnerability. The vector string highlights that the attack can be executed remotely (AV:N), requires low complexity (AC:L), does not need any special privileges (PR:N), and can be executed without user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), and the scope change is also high (SC:H), affecting the entire system (SI:H, SA:H).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: An attacker can exploit this vulnerability over the network without needing physical access to the system.
• SQL Injection: The attacker can inject malicious SQL code into the get_detalhes_cobranca.php endpoint, which is then executed by the database.

Exploitation Methods:

• Data Exfiltration: The attacker can extract sensitive information from the database.
• Data Manipulation: The attacker can modify database entries, leading to data integrity issues.
• Data Deletion: The attacker can delete critical data, causing data loss and potential service disruption.

3. Affected Systems and Software Versions

Affected Systems:

• WeGIA application versions prior to 3.2.12.

Vendor and Product Information:

• Vendor: LabRedesCefetRJ
• Product: WeGIA
• Affected Versions: < 3.2.12

4. Recommended Mitigation Strategies

Immediate Actions:

• Upgrade: All users are advised to upgrade to WeGIA version 3.2.12 or later, which addresses this vulnerability.
• Patch Management: Implement a robust patch management process to ensure timely updates and patches.

Long-Term Strategies:

• Input Validation: Ensure all user inputs are properly validated and sanitized to prevent SQL injection attacks.
• Parameterized Queries: Use parameterized queries or prepared statements to interact with the database.
• Web Application Firewall (WAF): Deploy a WAF to monitor and block malicious SQL injection attempts.
• Regular Audits: Conduct regular security audits and code reviews to identify and mitigate potential vulnerabilities.

5. Impact on European Cybersecurity Landscape

The vulnerability in WeGIA, a Web Manager for 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 losses, and reputational damage for these institutions.

Given the critical nature of the vulnerability and its potential impact, it is crucial for organizations using WeGIA to prioritize the upgrade to the patched version. The European Union's cybersecurity agencies should also disseminate this information widely to ensure all affected parties are aware and take appropriate actions.

6. Technical Details for Security Professionals

Vulnerability Details:

• Endpoint: get_detalhes_cobranca.php
• Vulnerability Type: SQL Injection
