感谢提醒这个问题。此方法已经不再使用了的。我已经屏蔽了。现在上传文件都是使用Api里面的控制器。 |
|
请问是哪个版本进行的修正？ |
|
我现在不记得了。总之升级到最新版代码。 |

\server\Application\Home\Controller\PageController.class.php第150行
$upload->allowExts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型$upload->allowExts 不是 Think\Upload 类的正确用法，导致文件后缀限制失效
并且方法里面没有进行$this->checkLogin();导致未登录上传文件，即前台gethell
本地起个服务器测试
上传图片，并抓包，将文件名改为
plzmyy.<>php生产环境下测试
修改为
$upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型参考链接：RoarCTF2019 simple_upload
