Unknown · Knowage Suite · CVE-2021-30211
**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/signup/update" API endpoint via the `surname` parameter. This allows for the execution of malicious scripts on the client-side.
**Recommendations**
For Knowage Suite version 7.3, as a temporary workaround, consider restricting access to the "/knowage/restful-services/signup/update" API endpoint or avoid using the `surname` parameter until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
