CVE-2026-1482 identifies a critical SQL injection vulnerability classified under CWE-89 in the Quatuor Evaluación de Desempeño (EDD) application, a performance evaluation tool developed by Gabinete Técnico de Programación. The vulnerability is an out-of-band (OOB) SQL injection affecting the 'Id_evaluacion' parameter in the '/evaluacion_objetivos_evalua_definido.aspx' page. Unlike traditional SQL injection, OOB SQLi allows attackers to extract data through external communication channels, such as DNS or HTTP requests, without the application directly returning query results. This makes detection more difficult and exploitation stealthier. The vulnerability affects all versions of the product and requires no authentication or user interaction, making it highly accessible to remote attackers. The CVSS 4.0 base score of 9.3 reflects its critical nature, with network attack vector, low complexity, no privileges or user interaction needed, and high impact on confidentiality and integrity. Exploiting this flaw could lead to unauthorized disclosure of sensitive information stored in the backend database, such as employee evaluations, personal data, or organizational metrics. No patches or fixes are currently available, and no known exploits have been reported in the wild, but the vulnerability's characteristics suggest a high likelihood of future exploitation. The vulnerability was assigned and published by INCIBE, indicating recognition by a European cybersecurity authority. The lack of direct data return by the application complicates detection and requires specialized monitoring and mitigation strategies.

For European organizations using Quatuor Evaluación de Desempeño (EDD), this vulnerability poses a significant risk to the confidentiality and integrity of sensitive performance evaluation data. Unauthorized extraction of such data could lead to privacy violations, reputational damage, and regulatory non-compliance, especially under GDPR. The out-of-band nature of the injection means attackers can stealthily exfiltrate data without triggering typical application-layer alarms. This could result in prolonged undetected breaches. Additionally, compromised data integrity could affect organizational decision-making processes reliant on accurate performance metrics. The vulnerability's ease of exploitation and lack of required authentication increase the attack surface, potentially affecting a wide range of users within affected organizations. The absence of patches means organizations must rely on immediate mitigations to prevent exploitation. Given the critical severity and potential for data leakage, this vulnerability could also be leveraged for further attacks, including privilege escalation or lateral movement within networks.

1. Immediate code remediation by developers to implement parameterized queries or prepared statements in the affected 'Id_evaluacion' parameter to prevent injection. 2. Conduct thorough input validation and sanitization on all user-supplied data, especially parameters interacting with the database. 3. Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection patterns, including out-of-band techniques. 4. Monitor network traffic for unusual outbound DNS or HTTP requests that could indicate OOB data exfiltration attempts. 5. Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 6. Implement logging and alerting mechanisms focused on anomalous database queries and application behavior. 7. Engage in regular security assessments and penetration testing targeting SQL injection vectors. 8. Coordinate with the vendor for timely patch releases and apply updates as soon as they become available. 9. Educate development and security teams about OOB SQL injection risks and detection methods. 10. Consider network segmentation to isolate critical systems and reduce lateral movement opportunities.
