In livewire/livewire `< 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: 'i...

### Problem Due to insufficient input validation, manipulated data saved in the bookmark toolbar of the backend user interface causes a general error state, blocking further access to the interface. Exploiting this vulnerability requires an administrator-level backend user account. ### Solution Update to TYPO3 versions 10.4.46 ELTS, 11.5.40 LTS, 12.4.21 LTS, 13.3.1 that fix the problem described. ### Credits Thanks to Hendrik Eichner who reported this issue and to TYPO3 core & security team members Oliver Hader and Benjamin Franzke who fixed the issue. ### References * [TYPO3-CORE-SA-2024-011](https://typo3.org/security/advisory/typo3-core-sa-2024-001)

A vulnerability was found in the resteasy-netty4 library arising from improper handling of HTTP requests using smuggling techniques. When an HTTP smuggling request with an ASCII control character is sent, it causes the Netty HttpObjectDecoder to transition into a BAD_MESSAGE state. As a result, any subsequent legitimate requests on the same connection are ignored, leading to client timeouts, which may impact systems using load balancers and expose them to risk.
