Multiple directory traversal vulnerabilities in FCKeditor before 2.6.4.1 allow remote attackers to create executable files in arbitrary directories via directory traversal sequences in the input to unspecified connector modules, as exploited in the wild for remote code execution in July 2009, related to the file browser and the editor/filemanager/connectors/ directory.
Multiple cross-site scripting (XSS) vulnerabilities in FCKeditor before 2.6.4.1 allow remote attackers to inject arbitrary web script or HTML via components in the samples (aka _samples) directory.
Cross-site scripting (XSS) vulnerability in the "Basic Toolbar Selection" in FCKEditor allows remote attackers to execute arbitrary JavaScript via the javascript: URI in the (1) href or (2) onmouseover attribute of the A HTML tag.
Incomplete blacklist vulnerability in connector.php in FCKeditor 2.0 and 2.2, as used in products such as RunCMS, allows remote attackers to upload and execute arbitrary script files by giving the files specific extensions that are not listed in the Config[DeniedExtensions][File], such as .php.txt.
