Livewire Remote Code Execution on File Uploads
In livewire/livewire prior to v2.12.7 and v3.5.2, the file extension of an uploaded file is guessed based on the MIME type. As a result, the actual file extension from the file name is not validated. An attacker can therefore bypass the validation by uploading a file with a valid MIME type (e.g., image/png) and a “.php” file extension.
If the following criteria are met, the attacker can carry out an RCE attack:
- Filename is composed of the original file name using
$file->getClientOriginalName() - Files stored directly on your server in a public storage disk
- Webserver is configured to execute “.php” files
PoC
In the following scenario, an attacker could upload a file called shell.php with an image/png MIME type and execute it on the remote server.
class SomeComponent extends Component
{
use WithFileUploads;
#[Validate('image|extensions:png')]
public $file;
public function save()
{
$this->validate();
$this->file->storeAs(
path: 'images',
name: $this->file->getClientOriginalName(),
options: ['disk' => 'public'],
);
}
