Name of the Vulnerable Software and Affected Versions nopCommerce version 4.2.0

Description The issue allows for privilege escalation through file upload in the Presentation/Nop.Web/Admin/Areas/Controllers/PluginController.cs via Admin/FacebookAuthentication/Configure. This is possible because it is possible to upload a crafted Facebook Auth plugin.

Recommendations For nopCommerce version 4.2.0, as a temporary workaround, consider disabling the file upload functionality in the PluginController.cs until a patch is available.

Avoid using the crafted Facebook Auth plugin in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
