Miggo AIRoot Cause Analysis

The analysis focused on the changes made to the DefaultServlet class, particularly how XSLT stylesheets are processed and how external entities are handled. The vulnerable function is identified as findXsltInputStream (and its variants) because it was directly modified to address the XXE vulnerability. The secureXslt method and SecureEntityResolver class are part of the mitigation and are not vulnerable themselves but are crucial in preventing the vulnerability.
