CVE-2025-53529 is a critical SQL Injection vulnerability identified in the WeGIA web management system developed by LabRedesCefetRJ, specifically affecting versions prior to 3.4.3. WeGIA is used by charitable institutions to manage their operations. The vulnerability exists in the /html/funcionario/profile_funcionario.php endpoint, where the id_funcionario parameter is improperly sanitized and validated before being incorporated into an SQL query. This lack of input validation allows an unauthenticated attacker to inject arbitrary SQL commands directly into the backend database. Exploitation of this flaw can lead to full compromise of the database confidentiality, integrity, and availability. The CVSS 3.1 base score is 9.8, reflecting its critical severity with network attack vector, no required privileges or user interaction, and complete impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the vulnerability’s characteristics make it highly exploitable and dangerous. The issue has been addressed in WeGIA version 3.4.3, where proper input sanitization and parameterized queries presumably mitigate the risk. This vulnerability falls under CWE-89, which covers improper neutralization of special elements used in SQL commands, a common and severe injection flaw that can lead to data breaches, unauthorized data manipulation, and denial of service.

For European organizations, especially charitable institutions or NGOs using the WeGIA platform, this vulnerability poses a significant risk. Successful exploitation could lead to unauthorized disclosure of sensitive donor and beneficiary data, manipulation or deletion of records, and disruption of critical organizational functions. Given the critical CVSS score and the fact that no authentication is required, attackers could remotely compromise systems without user interaction, potentially leading to large-scale data breaches and operational outages. This could result in reputational damage, regulatory penalties under GDPR due to exposure of personal data, and loss of trust from stakeholders. Additionally, attackers might leverage the compromised systems as footholds for further network intrusion or ransomware deployment. The impact extends beyond individual organizations to the broader ecosystem of charitable services in Europe, potentially affecting service delivery and funding.

Organizations using WeGIA should immediately verify their software version and upgrade to version 3.4.3 or later where the vulnerability is fixed. Until the upgrade is applied, implement web application firewall (WAF) rules specifically targeting SQL injection attempts on the /html/funcionario/profile_funcionario.php endpoint, focusing on the id_funcionario parameter. Conduct thorough input validation and sanitization on all user-supplied data, employing parameterized queries or prepared statements to prevent injection. Regularly audit logs for suspicious SQL errors or anomalous database queries. Employ network segmentation to limit database access and monitor for unusual outbound traffic that could indicate data exfiltration. Additionally, perform penetration testing and vulnerability scanning focused on injection flaws. Ensure backups are current and tested for integrity to enable recovery in case of data compromise. Finally, train development and security teams on secure coding practices to prevent similar issues in future releases.
