Name of the Vulnerable Software and Affected Versions Knowage versions 6.x.x through 8.1.7

Description The issue affects the Knowage suite, allowing authenticated users to exploit the templateName parameter in the /knowage/restful-services/dossier/importTemplateFile endpoint to download any file from the system. This is possible due to the lack of sanitization of the templateName parameter, enabling an attacker to use *../* and escape the directory where templates are normally placed. The result is that a low-privileged attacker can exfiltrate sensitive configuration files.

Recommendations For Knowage versions 6.x.x through 8.1.7, update to version 8.1.8 to resolve the issue. As a temporary workaround, consider restricting access to the /knowage/restful-services/dossier/importTemplateFile endpoint until the update can be applied. Additionally, limiting the use of the templateName parameter can help minimize the risk of exploitation.
