Descriptions

Knowage is an open source analytics and business intelligence suite. Starting in the 6.x.x branch and prior to version 8.1.8, the endpoint `/knowage/restful-services/dossier/importTemplateFile` allows authenticated users to upload `template file` on the server, but does not need any authorization to be reached. When the JSP file is uploaded, the attacker just needs to connect to `/knowageqbeengine/foo.jsp` to gain code execution on the server. By exploiting this vulnerability, an attacker with low privileges can upload a JSP file to the `knowageqbeengine` directory and gain code execution capability on the server. This issue has been patched in Knowage version 8.1.8.

Knowage es una suite de análisis e inteligencia de negocio de código abierto. A partir de la rama 6.x.x y antes de la versión 8.1.8, el endpoint `/knowage/restful-services/dossier/importTemplateFile` permite a los usuarios autenticados subir `template file` al servidor, pero no necesita ninguna autorización para ser alcanzado. Cuando se carga el archivo JSP, el atacante sólo necesita conectarse a `/knowageqbeengine/foo.jsp` para obtener la ejecución de código en el servidor. Aprovechando esta vulnerabilidad, un atacante con privilegios bajos puede cargar un archivo JSP en el directorio `knowageqbeengine` y obtener la capacidad de ejecutar código en el servidor. Este problema ha sido parcheado en la versión 8.1.8 de Knowage.
