Out-of-band SQL injection in Quatuor Performance Evaluation

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_acciones_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.
