Name of the Vulnerable Software and Affected Versions Knowage Suite version 7.3

Description The issue concerns Stored Cross-Site Scripting (XSS), where an attacker can inject arbitrary web script in the "/knowage/restful-services/documentnotes/saveNote" API endpoint via the nota parameter. This allows for the execution of malicious scripts on the victim's browser.

Recommendations For Knowage Suite version 7.3, as a temporary workaround, consider restricting access to the "/knowage/restful-services/documentnotes/saveNote" API endpoint to minimize the risk of exploitation. Avoid using the nota parameter in this endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
