The Apache folks have released version 2.4.9 of their ubiquitous web server.  This one fixes a couple of security vulnerabilities along with some other bug fixes, one in mod_log_config having to do with issues with truncated cookies and one in mod_dav that was a potential denial of service.  Expect most of the Linux distros to apply the appropriate fixes shortly, but if you are building from source or running on a platform that won't push the updates to you, go grab the update.

FCKEditor (now known as CKEditor [1]) is a popular full featured GUI editor many web sites use. For example, you frequently find it with blog systems like WordPress or as part of commenting/forum systems. As an additional feature, a filemanager can be added to allow users to upload images or other files. Sadly, while a very nice and functional plugin, this features if frequently not well secured and can be used to upload malicious files. We have seen some scans probing specifically for this file manager plugin:

HEAD /js/fckeditor/editor/filemanager/connectors/test.html 
HEAD /admin/FCKeditor/editor/filemanager/connectors/test.html 
HEAD /admin/FCKeditor/editor/fckeditor.html
HEAD /include/fckeditor/_samples/default.html 
HEAD /include/fckeditor/editor/filemanager/connectors/test.html
These requests did not set a user agent or a referrer. The following set did however use "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1;" and instead of a HEAD request it used a GET request, indicating that there are different distinct tools looking for the same vulnerability:
GET /editor/editor/filemanager/connectors/uploadtest.html HTTP/1.1
GET /editor/editor/filemanager/upload/test.html HTTP/1.1
GET /editor/editor/filemanager/browser/default/connectors/test.html HTTP/1.1
GET /editor/editor/filemanager/connectors/test.html HTTP/1.1
GET /admin/fckeditor/editor/filemanager/connectors/test.html HTTP/1.1
GET /FCKeditor/editor/filemanager/upload/test.html HTTP/1.1
GET /Fckeditor/editor/filemanager/browser/default/connectors/test.html HTTP/1.1
GET /admin/FCKeditor/editor/filemanager/connectors/uploadtest.html HTTP/1.1
GET /admin/FCKeditor/editor/filemanager/upload/test.html HTTP/1.1
GET /Fckeditor/editor/filemanager/connectors/test.html HTTP/1.1
GET /admin/fckeditor/editor/filemanager/browser/default/connectors/test.html HTTP/1.1
GET /FCKeditor/editor/filemanager/connectors/uploadtest.html HTTP/1.1

I am still looking for any samples of files these script attempt to upload. If you got any, please let use know.
