Carberp源代码泄露后续——黑掉黑客

上周，价值连城的银行盗号软件Carberp源代码遭泄露，高达1.8个G的数据，全球同行都在纷纷研究它的恶意代码。然而，一位法国的安全研究人员Steven K发现了独特的东西。他发现了Carberp自身的控制台存在很多安全漏洞。其中包括IP地址欺骗和远程代码控制。

研究人员发现了Carberp’s Panel中“data”这个变量存在远程代码执行漏洞，如下图所示：

同时他还写了PoC：

他已经成功利用漏洞攻陷了数据的用户名、密码、Auth Key。如下图所示：

Carberp源代码泄露后续——黑掉黑客

换句话说，可以利用这个漏洞去“坐享其成”，把使用Carberp的黑客黑掉，摘取黑客的革命成果。

第一张图和第二张图是什么编程语言?? 表示从来没见过呀…求科普~~

hume 2013-07-02

@米歇尔.奥巴马不是明显的PHP吗？

刘德华 2013-07-02

@hume 你读反了,应该倒着读,php,这样才对.

系甘噶啦，人地又5系写WEB出身噶，遍地漏洞好正常啦

马化腾 2013-07-02 7楼

这明显是作者放出之前的后门好不好算啥漏洞

helen 2013-07-03 8楼

我去泥码的,虽然后门不是我发现,但我想说这后门也太明显了吧?握曹作者写出这么牛B的木马居然连写个隐蔽点的后门都写不好,我表示深深的怀疑!神马Carberp有白金牛B?有GH0ST和灰鸽子牛B?你们都OUT啦!
