Nucleus has been reported to contain a flaw that may allow a remote attacker to execute arbitrary commands. The issue is supposedly due to the action.php, media.php, server.php and api_metaweblog.inc.php scripts not properly sanitizing user input supplied to the 'DIR_LIBS' variable. However, subsequent evaluation by another researcher indicates the DIR_LIBS variable is previously defined by config.php and not user controlled.
