### Upload tricks
- Use double extensions : `.jpg.php`
- Use double extensions : `.jpg.php, .png.php5`
- Use reverse double extension (useful to exploit Apache misconfigurations where anything with extension .php, but not necessarily ending in .php will execute code): `.php.jpg`
- Random uppercase and lowercase : `.pHp, .pHP5, .PhAr`
- Null byte (works well against `pathinfo()`)

### Filename vulnerabilities
Sometimes the vulnerability is not the upload but how the file is handled after. You might want to upload files with payloads in the filename.
- Time-Based SQLi Payloads: e.g. `poc.js'(select*from(select(sleep(20)))a)+'.extension`
- LFI Payloads: e.g. `image.png../../../../../../../etc/passwd`
- LFI/Path Traversal Payloads: e.g. `image.png../../../../../../../etc/passwd`
- XSS Payloads e.g. `'"><img src=x onerror=alert(document.domain)>.extension`
- File Traversal e.g. `../../../tmp/lol.png`
- Command Injection e.g. `; sleep 10;`
Also you upload:
- HTML/SVG files to trigger an XSS
- EICAR file to check the presence of an antivirus
### 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
If you are trying to upload files to a :
- PHP server, take a look at the .htaccess trick to execute code.
- ASP server, take a look at the .config trick to execute code.
- PHP server, take a look at the [.htaccess](https://github.com/swisskyrepo/PayloadsAllTheThings/tree/master/Upload%20Insecure%20Files/Configuration%20Apache%20.htaccess) trick to execute code.
- ASP server, take a look at the [web.config](https://github.com/swisskyrepo/PayloadsAllTheThings/tree/master/Upload%20Insecure%20Files/Configuration%20IIS%20web.config) trick to execute code.
Configuration files examples
- .htaccess
- web.config
- httpd.conf
- \_\_init\_\_.py

Alternatively you may be able to upload a JSON file with a custom scripts, try to overwrite a dependency manager configuration file.
