nuBuilder Local File Inclusion and Cross Site Scripting Vulnerabilities


Description   Two vulnerabilities have been identified in nuBuilder, which could be exploited by attackers to gain knowledge of sensitive information.
The first issue is caused by an input validation error in the "productionnu2/nuedit.php" script when processing the "f" parameter, which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected site.
The second vulnerability is caused by an input validation error in the "productionnu2/fileuploader.php" script when processing the "dir" parameter, which could be exploited by attackers to include or disclose the contents of local files with the privileges of the web server.
