iTop is an web based IT Service Management tool. In version 3.2.0, an attacker may send a URL to the server to trigger a PHP error. The next user trying to load this dashboard would encounter a crashed start page. Version 3.2.1 fixes the issue by checking the provided layout_class before saving the dashboard.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
