CVE-2025-67501 is a critical SQL Injection vulnerability identified in the WeGIA web management system developed by LabRedesCefetRJ, targeting Portuguese language institutions. The vulnerability resides in the /html/matPat/editar_categoria.php endpoint, specifically in the id_categoria parameter, which fails to properly validate and sanitize user input. This improper neutralization of special elements in SQL commands (CWE-89) allows attackers to inject malicious SQL payloads directly into the database query execution path. The vulnerability affects all versions prior to 3.5.5 and has been assigned a CVSS 4.0 score of 9.4, reflecting its critical severity. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H but note this is high privileges, so some level of privilege is needed), no user interaction (UI:N), and high impact on confidentiality, integrity, and availability (VC:H/VI:H/VA:H). This means an attacker with high privileges on the system can exploit this remotely without user interaction to execute arbitrary SQL commands, potentially leading to data leakage, unauthorized data manipulation, or complete compromise of the database. Although no known exploits are currently reported in the wild, the critical nature and ease of exploitation make this a significant threat. The vulnerability is fixed in WeGIA version 3.5.5, which properly sanitizes the id_categoria parameter to prevent injection. Organizations using affected versions should prioritize upgrading and reviewing their input validation mechanisms. Given WeGIA’s focus on Portuguese language users, the primary user base is likely in Portuguese-speaking countries and institutions, but European organizations with Portuguese ties or deployments should also be vigilant.

For European organizations, the impact of CVE-2025-67501 can be substantial, especially for those using WeGIA in academic, governmental, or institutional environments where sensitive data is managed. Exploitation could lead to unauthorized disclosure of confidential information, data tampering, or denial of service through database corruption. This compromises the integrity and availability of critical institutional data, potentially disrupting operations and damaging trust. Additionally, regulatory compliance risks arise under GDPR due to potential data breaches. The critical CVSS score reflects the high likelihood of severe consequences if exploited. Organizations with Portuguese language institutions or collaborations are particularly vulnerable, as they are more likely to deploy WeGIA. The need for high privileges to exploit somewhat limits the attack surface but does not eliminate risk, especially if internal threat actors or compromised accounts exist. The absence of known exploits in the wild currently provides a window for proactive mitigation.

1. Immediate upgrade to WeGIA version 3.5.5 or later, which contains the patch for this SQL Injection vulnerability. 2. Implement strict input validation and sanitization on all user-supplied data, especially parameters like id_categoria, using parameterized queries or prepared statements to prevent SQL injection. 3. Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. 4. Conduct code reviews and security audits focusing on input handling and database interactions within WeGIA and any custom extensions. 5. Monitor database logs and application logs for unusual queries or access patterns indicative of injection attempts. 6. Employ Web Application Firewalls (WAFs) with rules targeting SQL injection signatures to provide an additional layer of defense. 7. Educate internal users and administrators about the risks of privilege misuse and enforce strong access controls to reduce the risk of insider threats. 8. Develop and test incident response plans specific to database compromise scenarios to ensure rapid containment and recovery.
