Two vulnerabilities have been reported in the CKEditor and FCKeditor modules for Drupal, which can be exploited by malicious people to conduct cross-site scripting attacks and by malicious users or malicious people to compromise a vulnerable system.
1) Certain input when editing content is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed via the "text" parameter is not properly sanitised before being used in a text filter. This can be exploited to execute arbitrary PHP code.
Successful exploitation of this vulnerability for the 6.x versions requires the "access fckeditor" or "access ckeditor" permissions and the "PHP Filter" module to be enabled.
The vulnerabilities are reported in the following products:
* FCKeditor module versions 6.x-2.x prior to 6.x-2.3.
* CKEditor module versions 6.x-1.x prior to 6.x-1.9.
* CKEditor module versions 7.x-1.x prior to 7.x-1.7.
