CVE-2025-67501 is a critical SQL Injection vulnerability identified in the WeGIA web management system developed by LabRedesCefetRJ, primarily 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 that the backend database executes directly. The flaw affects all WeGIA versions prior to 3.5.5, with the vendor releasing a fix in version 3.5.5. The CVSS 4.0 score of 9.4 reflects a critical severity due to network attack vector (AV:N), low attack complexity (AC:L), no required authentication (AT:N), and no user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability with high scope and impact metrics, meaning an attacker can fully compromise the database, extract sensitive data, alter records, or disrupt service. Although no known exploits are currently reported in the wild, the ease of exploitation and critical impact necessitate urgent remediation. The vulnerability is particularly concerning for institutions relying on WeGIA for managing sensitive institutional data, including educational and administrative records. The technical root cause is insufficient input validation and sanitization of the id_categoria parameter, which should be mitigated by parameterized queries or prepared statements. The vulnerability disclosure date is December 9, 2025, with the CVE assigned shortly before. Given the open-source nature of WeGIA and its focus on Portuguese-speaking users, the threat landscape includes educational institutions and organizations in Portuguese-speaking European communities.

The impact of CVE-2025-67501 on European organizations using WeGIA is significant. Successful exploitation allows attackers to execute arbitrary SQL commands on the backend database, leading to unauthorized data access, data manipulation, or deletion. This compromises the confidentiality, integrity, and availability of critical institutional data, potentially exposing sensitive personal information, academic records, or administrative data. For educational institutions and public sector organizations, such breaches can result in regulatory penalties under GDPR, reputational damage, and operational disruptions. The vulnerability requires no authentication or user interaction, increasing the risk of automated or remote exploitation. Given the critical CVSS score and the nature of the vulnerability, attackers could leverage this flaw to establish persistent access, escalate privileges, or pivot within the network. The lack of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for mitigation. European organizations with Portuguese language ties or those using WeGIA for institutional management are particularly vulnerable, as attackers may target these environments for espionage, data theft, or sabotage. The impact extends beyond data loss to potential compliance violations and loss of trust from stakeholders.

To mitigate CVE-2025-67501, European organizations should immediately upgrade WeGIA installations to version 3.5.5 or later, where the vulnerability is patched. If immediate upgrading is not feasible, organizations should implement strict input validation and sanitization on the id_categoria parameter, employing parameterized queries or prepared statements to prevent SQL injection. Web application firewalls (WAFs) can be configured to detect and block common SQL injection payloads targeting the vulnerable endpoint. Regularly audit and monitor database logs for unusual queries or access patterns indicative of exploitation attempts. Conduct code reviews and security testing on custom deployments or forks of WeGIA to ensure no residual injection flaws remain. Additionally, organizations should enforce network segmentation to limit database access and apply the principle of least privilege to database accounts used by the application. Employee training on secure coding and awareness of injection attacks can help prevent similar vulnerabilities in future development. Finally, maintain up-to-date backups of critical data to enable recovery in case of data corruption or deletion caused by exploitation.
