Summary
Knowage is an open source analytics and business intelligence suite. In versions from 6.x.x to prior to 8.1.8, the endpoint `/knowage/restful-services/dossier/importTemplateFile` allows authenticated users to upload template files to the server without requiring authorization, enabling code execution on the server.
Risk Assessment
An attacker with low privileges can upload a JSP file to the `knowageqbeengine` directory, leading to code execution capabilities on the server, posing a serious security threat to the organization.
Recommendation
It is recommended to upgrade Knowage to version 8.1.8 or later to mitigate this vulnerability and implement appropriate security measures to restrict access to critical endpoints.
Original NVD description (English source)
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.
