Technical details

A server-side template injection vulnerability exists in the system notification template rendering engine. An authenticated System Administrator with template management privileges can store a crafted template containing template expressions that the engine evaluates, leading to remote code execution on the appliance. The vulnerability requires high-privilege authentication but no additional user interaction once the malicious template is created and a notification is triggered.

Affected products

Kiteworks Core before 9.5.1
