存储型XSS(前台及后台)

前台的客户留言处存在存储xss

是由于后端未对用户的留言进行xss的过滤,直接将留言存入数据库

后台的新增栏目与发布文章处都存在存储xss,插入payload后前台访问就会触发

未授权

上传接口和上传文件的访问存在未授权

在未登录的情况下可上传文件

接口:/upload/uploadFile

上传的文件在知道文件名的情况下可任意访问,不用登录

可通过…/跨目录访问资源文件夹下的所有文件:

结合以上两点可以未授权上传html文件,文件内容是恶意的xss payload,然后将html文件的链接发给网站使用者,当网站使用者点击链接后,就会触发恶意js代码导致cookie窃取等危害。
