Input passed to the "context[path_to_root]" parameter in scripts/update_trailer.php is not properly verified before being used to include files. This can be exploited to execute arbitrary PHP code by including files from local or external resources. Successful exploitation requires that "register_globals" is enabled. The vulnerability is confirmed in version 8.11rc30. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly verified.
