CVE-2025-53527 is a high-severity SQL Injection vulnerability affecting the WeGIA web management software developed by LabRedesCefetRJ, specifically versions from 3.3.3 up to but not including 3.4.1. The vulnerability exists in the 'almox' parameter of the /controle/relatorio_geracao.php endpoint. It is a Time-Based Blind SQL Injection, meaning an attacker can inject malicious SQL payloads that cause the database to delay its response based on the injected query logic, allowing the attacker to infer data values without direct output. This improper neutralization of special elements used in SQL commands (CWE-89) enables attackers to execute arbitrary SQL queries on the backend database. The impact can include unauthorized data access, data exfiltration, or further exploitation depending on the database configuration and privileges of the application. The vulnerability requires no user interaction and no authentication, making it remotely exploitable over the network with low attack complexity. The CVSS 4.0 score is 8.3 (high), reflecting the critical nature of the flaw with network attack vector, no privileges required, and high impact on confidentiality. The issue was publicly disclosed on July 7, 2025, and fixed in WeGIA version 3.4.1. No known exploits are currently reported in the wild, but the vulnerability's characteristics make it a significant risk if left unpatched.

For European organizations using WeGIA to manage charitable institutions, this vulnerability poses a serious risk to the confidentiality and integrity of sensitive data. Exploitation could lead to unauthorized access to donor information, financial records, or personal data of beneficiaries, potentially violating GDPR and other data protection regulations. The ability to execute arbitrary SQL commands could also allow attackers to manipulate or delete data, disrupting operations and damaging organizational reputation. Since WeGIA is a specialized tool for charitable institutions, the impact extends beyond data loss to potential harm to vulnerable populations relying on these services. The lack of authentication requirement increases the risk of automated or widespread attacks. Organizations could face regulatory fines, legal liabilities, and loss of trust if this vulnerability is exploited.

European organizations should immediately verify their WeGIA version and upgrade to version 3.4.1 or later where the vulnerability is patched. If immediate upgrade is not feasible, implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'almox' parameter, especially time-based blind injection attempts. Conduct thorough input validation and parameterized queries in any custom integrations with WeGIA. Regularly audit logs for suspicious query patterns or anomalies in database response times. Limit database user privileges associated with the WeGIA application to the minimum necessary to reduce potential damage. Additionally, perform penetration testing focused on SQL injection vectors to confirm the absence of exploitable injection points. Finally, ensure incident response plans include scenarios for SQL injection attacks to enable rapid containment and remediation.
