CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

KnowledgeView Editorial and Management application contains a reflected cross-site scripting vulnerability that can allow an attacker to inject arbitrary HTML content (including script) via the vulnerable query string parameter username.

A remote unauthenticated attacker can conduct a cross-site scripting attack, which may be used to result in information leakage, privilege escalation, and/or denial of service.

We are currently unaware of a practical solution to this problem. Please consider the following workaround.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the web interface using stolen credentials from a blocked network location.
