CVE-2026-1474 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' and 'Id_evaluacion' en ‘/evaluacion_inicio.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-2026-1474 represents a critical out-of-band sql injection flaw within the Performance Evaluation application developed by Gabinete Técnico de Programación. This vulnerability specifically targets the parameter handling mechanism in the /evaluacion_inicio.aspx endpoint where the Id_usuario and Id_evaluacion parameters are processed. The out-of-band nature of this vulnerability distinguishes it from traditional sql injection attacks as it leverages external communication channels to exfiltrate data rather than relying on direct response mechanisms from the vulnerable application. This architectural characteristic makes the vulnerability particularly concerning as it bypasses many conventional detection and prevention measures that depend on monitoring application responses for malicious sql payloads.
The technical flaw manifests when user-supplied input containing sql injection payloads is processed through the Id_usuario and Id_evaluacion parameters without proper sanitization or parameterized query execution. Attackers can craft malicious inputs that, when processed by the application, trigger database queries that communicate with external servers to deliver sensitive information. This methodology aligns with CWE-649 which specifically addresses weaknesses in database communication protocols and external data handling mechanisms. The vulnerability exploits the application's failure to implement proper input validation and sanitization, allowing attackers to construct sql commands that leverage database features such as out-of-band communication capabilities to extract data through DNS requests or other external channels.
The operational impact of this vulnerability extends beyond simple data theft to encompass comprehensive system compromise and information disclosure. An attacker exploiting this vulnerability can extract complete database schemas, user credentials, personal information, and other sensitive data stored within the application's database without leaving obvious traces in application logs or direct response data. This capability directly violates the confidentiality principle of the CIA triad and can result in severe consequences including identity theft, financial fraud, regulatory compliance violations, and reputational damage. The attack vector is particularly dangerous because it operates through external channels that are often not monitored by traditional security controls, making detection extremely challenging for security operations teams.
Mitigation strategies for CVE-2026-1474 must address both the immediate code-level vulnerabilities and implement broader architectural security controls. The primary recommendation involves implementing proper parameterized queries or prepared statements for all database interactions, specifically targeting the Id_usuario and Id_evaluacion parameters in the affected endpoint. Additionally, implementing strict input validation with whitelisting approaches for these parameters will prevent malicious payloads from being processed. Network-level controls should include monitoring for unusual external communications, particularly DNS requests or HTTP connections to suspicious external domains that may indicate data exfiltration attempts. Organizations should also consider implementing web application firewalls with sql injection detection capabilities and establishing comprehensive logging and monitoring of database access patterns. The remediation process should follow ATT&CK framework guidance for T1190 (Exploit Public-Facing Application) and T1071.004 (Application Layer Protocol: DNS) to ensure comprehensive protection against similar attack vectors. Regular security assessments and penetration testing should be conducted to verify the effectiveness of implemented controls and identify potential new attack surfaces that may emerge from similar vulnerabilities.
