AppScan安全漏洞解决方案

1.会话cookie 中缺少HttpOnly 属性。  
修复任务： 向所有会话cookie 添加“HttpOnly”属性 
  解决方案，过滤器中， 

HttpServletResponse response2 = (HttpServletResponse)response;
//httponly是微软对cookie做的扩展,该值指定 Cookie 是否可通过客户端脚本访问,
//解决用户的cookie可能被盗用的问题,减少跨站脚本攻击
response2.setHeader( "Set-Cookie", "name=value; HttpOnly");

2.跨站点请求伪造。修复任务： 拒绝恶意请求。  
解决方案，过滤器中 

//HTTP 头设置 Referer过滤
String referer = request2.getHeader("Referer");   //REFRESH
if(referer!=null && referer.indexOf(basePath)<0){            request2.getRequestDispatcher(request2.getRequestURI()).forward(request2, response);
}

3.Autocomplete HTML Attribute Not Disabled for Password Field 
修复任务： Correctly set the "autocomplete" attribute to "off" 

密  码：
<input name="userinfo.userPwd" type="password"  autocomplete = "off"/>

4.HTML 注释敏感信息泄露。删除注释信息。 

5.跨站点脚本编制，SQL 盲注，通过框架钓鱼，链接注入（便于跨站请求伪造）。修复任务： 过滤掉用户输入中的危险字符 

private String filterDangerString(String value) {
        if (value == null) {
            return null;
        }
        value = value.replaceAll("\\|", "");

        value = value.replaceAll("&", "&");

        value = value.replaceAll(";", "");

        value = value.replaceAll("@", "");

        value = value.replaceAll("'", "");

        value = value.replaceAll("\"", "");

        value = value.replaceAll("\\'", "");

        value = value.replaceAll("\\\"", "");

        value = value.replaceAll("<", "&lt;");

        value = value.replaceAll(">", "&gt;");

        value = value.replaceAll("\\(", "");

        value = value.replaceAll("\\)", "");

        value = value.replaceAll("\\+", "");

        value = value.replaceAll("\r", "");

        value = value.replaceAll("\n", "");

        value = value.replaceAll("script", "");

        value = value.replaceAll("%27", "");
        value = value.replaceAll("%22", "");
        value = value.replaceAll("%3E", "");
        value = value.replaceAll("%3C", "");
        value = value.replaceAll("%3D", "");
        value = value.replaceAll("%2F", "");
        return value;
    }
