齐博cms整站系统（原PHP168）配置不当导致任意用户登陆，比如cms管理员等。 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.2cto.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 $ php uc.php haidian.10000tc.com synlogin [+] UC_KEY 'null' can use .
