CVE-2025-53527 is a high-severity SQL Injection vulnerability (CWE-89) affecting the WeGIA web management system 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, where improper neutralization of special elements in SQL commands allows an attacker to perform Time-Based Blind SQL Injection attacks. This type of injection enables an attacker to craft malicious SQL queries that can be executed by the backend database without proper validation or sanitization. Exploiting this vulnerability can lead to unauthorized access to sensitive data stored in the database, such as user information or institutional records. Depending on the database configuration and privileges, it may also allow further exploitation such as data modification or escalation of privileges. The vulnerability does not require user interaction and can be exploited remotely over the network without authentication, increasing its risk profile. The CVSS 4.0 base score of 8.3 reflects the high impact on confidentiality and integrity, with low attack complexity and no need for privileges or user interaction. Although no known exploits are currently reported in the wild, the vulnerability is publicly disclosed and fixed in version 3.4.1 of WeGIA, making it critical for users to update promptly. The technical details confirm the vulnerability was reserved and published in early July 2025, indicating recent discovery and disclosure. Given the nature of Time-Based Blind SQL Injection, detection may be challenging without proper monitoring, as it relies on timing differences rather than direct error messages or data leakage.

For European organizations using WeGIA to manage charitable institutions, this vulnerability poses significant risks. Unauthorized data access could lead to exposure of sensitive donor information, financial records, and internal reports, potentially violating GDPR and other data protection regulations. Data integrity could be compromised if attackers modify records, undermining trust and operational continuity. The availability of the system could also be affected if attackers exploit the vulnerability to perform denial-of-service attacks via resource-intensive queries. Given that WeGIA is a specialized tool for charitable institutions, the impact extends beyond technical damage to reputational harm and legal liabilities. Organizations may face regulatory fines and loss of stakeholder confidence if breaches occur. The lack of required authentication and user interaction means attackers can exploit this vulnerability remotely and stealthily, increasing the likelihood of targeted attacks against European NGOs and charities that rely on WeGIA for their operations.

European organizations should immediately upgrade WeGIA installations to version 3.4.1 or later, where the vulnerability is patched. If immediate upgrade is not feasible, implement web application firewall (WAF) rules specifically designed to detect and block SQL injection patterns targeting the 'almox' parameter and the /controle/relatorio_geracao.php endpoint. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters used in SQL queries. Employ parameterized queries or prepared statements to prevent injection. Monitor logs for unusual time delays or anomalies indicative of Time-Based Blind SQL Injection attempts. Regularly audit database permissions to ensure minimal privileges are granted to the application, limiting potential damage. Additionally, perform security assessments and penetration testing focused on injection vulnerabilities to validate the effectiveness of mitigations. Finally, ensure incident response plans include procedures for SQL injection attack scenarios to minimize impact if exploitation occurs.
