Improper Control of Generation of Code ('Code Injection')


Severity High
Score 7.5/10


Unrestricted file upload vulnerability in editor/filemanager/browser/default/connectors/php/connector.php in FCKeditor 2.2, as used in Falt4 CMS, Nuke ET, and other products, allows remote attackers to execute arbitrary code by creating a file with PHP sequences preceded by a ZIP header, uploading this file via a FileUpload action with the application/zip content type, and then accessing this file via a direct request to the file in UserFiles/File/, probably a related issue to CVE-2005-4094. NOTE: some of these details are obtained from third party information.

CWE-94 - Code Injection

Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
