CVE-2024-24752

Bref enable serverless PHP on AWS Lambda. When Bref is used with the Event-Driven Function runtime and the handler is a `RequestHandlerInterface`, then the Lambda event is converted to a PSR7 object. During the conversion process, if the request is a MultiPart, each part is parsed and for each which contains a file, it is extracted and saved in `/tmp` with a random filename starting with `bref_upload_`. The flow mimics what plain PHP does but it does not delete the temporary files when the request has been processed. An attacker could fill the Lambda instance disk by performing multiple MultiPart requests containing files. This vulnerability is patched in 2.1.13.

Summary
  • (es) Bref habilita PHP sin servidor en AWS Lambda. Cuando se usa Bref con el tiempo de ejecución de la función controlada por eventos y el controlador es "RequestHandlerInterface", el evento Lambda se convierte en un objeto PSR7. Durante el proceso de conversión, si la solicitud es MultiPart, cada parte se analiza y, para cada una de las que contiene un archivo, se extrae y se guarda en `/tmp` con un nombre de archivo aleatorio que comienza con `bref_upload_`. El flujo imita lo que hace el PHP plano pero no elimina los archivos temporales cuando se procesa la solicitud. Un atacante podría llenar el disco de la instancia de Lambda realizando múltiples solicitudes MultiPart que contengan archivos. Esta vulnerabilidad está parcheada en 2.1.13.
