Description:
rgod has discovered a vulnerability in Geeklog, which can be exploited by malicious people to compromise a vulnerable system.
The problem is that it is possible to upload files with multiple file extensions to a location inside the web root via the fckeditor/editor/filemanager/browser/mcpuk/connectors/php/connector.php script. This can e.g. be exploited to execute arbitrary PHP code by uploading a malicious PHP script to the "images/library/File" directory.
Example:
[file].php.zip
Successful exploitation requires an Apache server with the "mod_mime" module installed.
The vulnerability has been confirmed in version 1.4.0sr3. Other versions may also be affected.
Solution:
Update to version 1.4.0sr4.
