Cross-Site Scripting: Reflected Vulnerability in index.jsp

The method _jspService() in index.jsp sends unvalidated data to a web browser on line 131, which can result in the browser executing malicious code.

Explanation:

Cross-site scripting (XSS) vulnerabilities occur when:

1. Data enters a web application through an untrusted source. In the case of Reflected XSS, the untrusted source is typically a web request, while in the case of Persisted (also known as Stored) XSS it is typically a database or other back-end datastore.

In this case the data enters at getHeader() in ProxyHttpServletRequestWrapper.java at line 41.

2. The data is included in dynamic content that is sent to a web user without being validated.

In this case the data is sent at println() in index.jsp at line 131.
