### 简要描述：
RT
### 详细说明：
以前老版本一直对XSS没啥防御，也就没好意思发。最近看手头上的一个eyou信箱升级到eyou5了。发现新版本开始对XSS进行过滤了就测试了一下，发现了一点问题。
#1
测试单个XSS攻击向量，如：
```
<img src=x onerror=alert(1)>
```
还是可以抵挡的住的。
#2
不过情况稍微复杂一些，你们的过滤规则就招架不住了。如：
```
<script>alert(0)</script>
<script>confirm(1)</script>
<script>prompt(2)</script>
<script>\u0061\u006C\u0065\u0072\u0074(3)</script>

面对较为复杂的场景时，你们的过滤规则就招架不住了。

因为是过滤器设计上的问题，所以我相信你们所有的版本都存在这个缺陷。如果重现上有困难可以发乌云短消息联系我。
