Direct static code injection vulnerability in the modify_config action in admin.php for PHP-Stats 0.1.9.1 and earlier allows remote authenticated administrators to execute arbitrary PHP code via the option_new[compatibility_mode] parameter, which is not filtered before being stored in config.php. NOTE: this vulnerability can be exploited by remote unauthenticated attackers in conjunction with the option[admin_pass] authentication bypass vulnerability.
