CVE-2026-1483 in Evaluación de Desempeño
Summary
by MITRE • 01/27/2026
An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' in '/evaluacion_objetivos_ver_auto.aspx', could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information.

The vulnerability identified as CVE-2026-1483 represents a critical out-of-band sql injection flaw within the Performance Evaluation application developed by Gabinete Técnico de Programación. This specific weakness manifests in the 'Id_usuario' parameter of the '/evaluacion_objetivos_ver_auto.aspx' endpoint, creating a significant security risk that directly impacts the confidentiality of database-stored information. The vulnerability classifies under CWE-649 as an out-of-band sql injection, where attackers can extract data through external communication channels rather than relying on direct response mechanisms from the vulnerable application.
The technical implementation of this flaw allows malicious actors to construct sql queries that can communicate with external servers to exfiltrate database contents. This approach bypasses traditional input validation and output encoding defenses since the data extraction occurs through separate communication channels, making detection more challenging for security monitoring systems. The affected parameter 'Id_usuario' serves as the primary attack vector where unsanitized user input gets directly incorporated into sql query construction without proper sanitization or parameterization mechanisms.
Operationally, this vulnerability presents severe implications for organizations relying on the Performance Evaluation system for personnel assessment and performance tracking. Attackers could potentially extract sensitive employee data, including personal identification information, performance metrics, evaluation results, and other confidential organizational data. The out-of-band nature of the attack means that data exfiltration occurs through covert channels that may not be immediately apparent to network monitoring systems, allowing prolonged unauthorized access to database resources. This vulnerability directly violates security principles outlined in the att&ck framework under technique T1071.004 for application layer protocol evasion and T1041 for data exfiltration through external systems.
Organizations should implement immediate mitigations including comprehensive input validation and parameterized query construction for all database interactions. The application should be updated to use prepared statements or parameterized queries that separate sql code from user input, preventing injection attacks regardless of input content. Network segmentation and monitoring should be enhanced to detect unusual external communication patterns that may indicate out-of-band data exfiltration attempts. Additionally, regular security assessments should validate that all input parameters are properly sanitized and that no similar vulnerabilities exist in other application endpoints. The mitigation strategy must align with industry standards including owasp top ten and iso 27001 security controls for protecting sensitive information and maintaining data confidentiality.
