CVE-2022-36065

GrowthBook is an open-source platform for feature flagging and A/B testing. With some self-hosted configurations in versions prior to 2022-08-29, attackers can register new accounts and upload files to arbitrary directories within the container. If the attacker uploads a Python script to the right location, they can execute arbitrary code within the container. To be affected, ALL of the following must be true: Self-hosted deployment (GrowthBook Cloud is unaffected); using local file uploads (as opposed to S3 or Google Cloud Storage); NODE_ENV set to a non-production value and JWT_SECRET set to an easily guessable string like `dev`. This issue is patched in commit 1a5edff8786d141161bf880c2fd9ccbe2850a264 (2022-08-29). As a workaround, set `JWT_SECRET` environment variable to a long random string. This will stop arbitrary file uploads, but the only way to stop attackers from registering accounts is by updating to the latest build.

GrowthBook es una plataforma de código abierto para el marcado de características y las pruebas A/B. Con algunas configuraciones auto-alojadas en versiones anteriores al 29-08-2022, los atacantes pueden registrar nuevas cuentas y subir archivos a directorios arbitrarios dentro del contenedor. Si el atacante sube un script de Python a la ubicación correcta, puede ejecutar código arbitrario dentro del contenedor. Para ser afectado, TODO lo siguiente debe ser cierto: despliegue auto-alojado (GrowthBook Cloud no está afectado); el uso de cargas de archivos locales (en lugar de S3 o Google Cloud Storage); NODE_ENV establecido a un valor no de producción y JWT_SECRET establecido a una cadena fácilmente adivinable como "dev". Este problema está parcheado en el commit 1a5edff8786d141161bf880c2fd9ccbe2850a264 (2022-08-29). Como mitigación, establezca la variable de entorno "JWT_SECRET" a una cadena larga y aleatoria. Esto detendrá la carga de archivos arbitrarios, pero la única forma de evitar que los atacantes registren cuentas es actualizando a la última versión.
