WordPress最新版本3.3.2存在一个双字节编码的存储型跨站漏洞,可以bypass内置的filter机制,利用起来有点鸡肋,细节如下
1登录管理账户
2单击分类
3填写跨站参数,并用burp suite拦截请求
4输入%253cscript%253ealert%25281%2529%253c%252fscript%253e可以直接bypass

BURP请求数据包

复制代码
代码如下:

长沙网络推广鸡肋,鸡肋中的鸡肋,minminmsn同学应该是翻译自国外的文章,没有经过详细的测试,wordpress默认的filter机制对管理员权限是不过滤的,所以不仅仅在分类里存在跨站,其他地方更是跨站多多。也许有其他的猥琐的用途吧。
