How to Fix CVE-2024-47823

To remediate this vulnerability, upgrade all affected Livewire/livewire dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

livewire/livewire fixed: 3.5.2
Upgrade livewire/livewire to 3.5.2
livewire/livewire fixed: 2.12.7
Upgrade livewire/livewire to 2.12.7
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for livewire/livewire

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-47823, inspect your project dependencies for Livewire/livewire:

inspect dependencies for livewire/livewire

Analyze the terminal output to locate any version of Livewire/livewire in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.5.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Livewire/livewire, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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. ```php 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'], ); } } ```
