CVE-2026-1473 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_competencias_evalua.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.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified as CVE-2026-1473 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_competencias_evalua.aspx' endpoint, creating a significant security risk that directly impacts the confidentiality of stored database information. The out-of-band nature of this injection vulnerability distinguishes it from traditional sql injection attacks by enabling attackers to extract data through external communication channels rather than relying on direct data return mechanisms from the vulnerable application.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the application's parameter handling mechanism. When the 'Id_usuario' parameter receives malicious input, the application fails to properly escape or filter special sql characters and commands, allowing an attacker to inject arbitrary sql payloads. The out-of-band characteristic means that successful exploitation enables data extraction through secondary channels such as dns requests, http requests, or other external communication methods that bypass the application's normal response mechanisms. This approach provides attackers with a stealthy method of data exfiltration that is often difficult to detect through conventional network monitoring tools.
The operational impact of this vulnerability extends beyond simple data theft to encompass potential system compromise and regulatory compliance violations. Attackers exploiting this weakness could gain access to sensitive user information, evaluation records, and potentially system credentials stored within the database. The confidentiality of the entire evaluation database becomes compromised, affecting not only individual privacy but also organizational integrity and trust. Organizations relying on this application for performance evaluation processes face significant risk of data breaches that could impact employee records, evaluation results, and institutional data governance policies.
Security mitigations for CVE-2026-1473 should focus on implementing robust input validation and parameterized query mechanisms throughout the application stack. The primary remediation involves sanitizing all user inputs through proper escaping techniques and implementing prepared statements or parameterized queries to prevent sql injection exploitation. Network-level protections including web application firewalls and intrusion detection systems should be configured to monitor for suspicious external communication patterns that may indicate out-of-band data extraction attempts. Additionally, regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components, aligning with industry standards such as those referenced in cwe-94 and the mitre att&ck framework's command and control tactics. The vulnerability classification aligns with cwe-89 sql injection and cwe-121 buffer overflow patterns, emphasizing the need for comprehensive defensive measures including proper access controls, database permissions management, and regular security patching of the underlying application infrastructure.
