CVE-2025-53937 is a critical SQL Injection vulnerability affecting WeGIA, an open-source web management platform primarily targeting Portuguese-speaking charitable institutions. The vulnerability exists in the /controle/control.php endpoint, specifically within the 'cargo' parameter, in versions prior to 3.4.5. SQL Injection (CWE-89) occurs when user-supplied input is improperly neutralized before being included in SQL queries, allowing attackers to manipulate the database commands executed by the application. In this case, the lack of proper sanitization or parameterization of the 'cargo' parameter enables an attacker to inject arbitrary SQL code. Exploiting this flaw could allow unauthorized disclosure of sensitive data, modification or deletion of database records, and potentially full compromise of the backend database system. The vulnerability has a CVSS 4.0 base score of 9.4, indicating critical severity, with network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make this a significant threat. The issue was addressed in WeGIA version 3.4.5, which includes patches to properly neutralize the 'cargo' parameter input and prevent SQL Injection attacks.

For European organizations using WeGIA, particularly charitable and non-profit entities serving Portuguese-speaking communities or collaborating internationally, this vulnerability poses a severe risk. Successful exploitation could lead to unauthorized access to donor information, financial records, and internal communications, undermining confidentiality and trust. Data integrity could be compromised by unauthorized modifications, potentially disrupting operations or causing legal compliance issues under GDPR. Availability of the service could also be impacted if attackers execute destructive SQL commands or launch denial-of-service conditions via the database. Given WeGIA's focus on charitable institutions, the impact extends beyond technical damage to reputational harm and potential loss of funding. Additionally, attackers could leverage the compromised database as a foothold for further network intrusion. The lack of required authentication and user interaction increases the risk of automated exploitation attempts, emphasizing the need for prompt remediation.

European organizations should immediately verify their WeGIA version and upgrade to 3.4.5 or later to apply the official patch. Where immediate upgrade is not feasible, implement Web Application Firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'cargo' parameter. Conduct thorough input validation and parameterized query enforcement in custom deployments or integrations. Regularly audit database logs for anomalous queries or access patterns indicative of exploitation attempts. Employ network segmentation to limit database exposure and restrict access to trusted hosts only. Additionally, perform security awareness training for administrators managing WeGIA instances to recognize signs of compromise. Organizations should also ensure comprehensive backups are in place to enable recovery in case of data corruption or loss. Finally, monitor threat intelligence feeds for emerging exploit code or attack campaigns targeting this vulnerability.
