影响版本: 2.4.8c 
缺陷分析
There is no sanitation on the input of the name variable. This allows  
malicious scripts to be added. This is a stored XSS. 
解决方案
 
升级到新版2.4.8d 
 
name=[XSS] 
测试示例
The script can be added right in the page, there is no filtering of  
input. This can easily be exploited if the email address used is added  
to the "approved posters" list.
