# Upload
|
|
|
|
Uploaded files may pose a significant risk if not handled correctly. A remote attacker could send a multipart/form-data POST request with a specially-crafted filename or mime type and execute arbitrary code.

|
|

|
|
|
|
### Other extensions
|
|
|
|
```powershell
|
|
asp : .asp, .aspx
|
|
perl: .pl, .pm, .cgi, .lib
|
|
jsp : .jsp, .jspx, .jsw, .jsv, .jspf
|
|
Coldfusion: .cfm, .cfml, .cfc, .dbm
|
|
```
|
|
|
|
### Upload tricks
|
|
|
|
- Null byte (eg: shell.php%00.gif, shell.php%00.png), works well against `pathinfo()`
|
|
- Mime type, change `Content-Type : application/x-php` or `Content-Type : application/octet-stream` to `Content-Type : image/gif`
|
|
|
|
### Picture upload with LFI
|
|
|
|
Valid pictures hosting PHP code. Upload the picture and use a local file inclusion to execute the code. The shell can be called with the following command : `curl 'http://localhost/test.php?0=system' --data "1='ls'"`.
|
|
|
|
- Picture Metadata, hide the payload inside a comment tag in the metadata.
|
|
- Picture Resize, hide the payload within the compression algorithm in order to bypass a resize. Also defeating `getimagesize()` and `imagecreatefromgif()`.
|
|
|
|
### Configuration Files
|
|
|
|
- .htaccess
|
|
- web.config
|
|
- httpd.conf
|
|
- \_\_init\_\_.py
|
|
|
|
|
|
### CVE - Image Tragik
|
|
|
|
```powershell
|
|
HTTP Request
|
|
Reverse Shell
|
|
Touch command
|
|
```
