Descriptions

Mealie is a self hosted recipe manager and meal planner. Prior to 1.4.0, the safe_scrape_html function utilizes a user-controlled URL to issue a request to a remote server, however these requests are not rate-limited. While there are efforts to prevent DDoS by implementing a timeout on requests, it is possible for an attacker to issue a large number of requests to the server which will be handled in batches based on the configuration of the Mealie server. The chunking of responses is helpful for mitigating memory exhaustion on the Mealie server, however a single request to an arbitrarily large external file (e.g. a Debian ISO) is often sufficient to completely saturate a CPU core assigned to the Mealie container. Without rate limiting in place, it is possible to not only sustain traffic against an external target indefinitely, but also to exhaust the CPU resources assigned to the Mealie container. This vulnerability is fixed in 1.4.0.

Mealie es un administrador de recetas y planificador de comidas autónomo. Antes de 1.4.0, la función safe_scrape_html utiliza una URL controlada por el usuario para emitir una solicitud a un servidor remoto; sin embargo, estas solicitudes no tienen una velocidad limitada. Si bien se están realizando esfuerzos para evitar DDoS implementando un tiempo de espera en las solicitudes, es posible que un atacante emita una gran cantidad de solicitudes al servidor que se manejarán en lotes según la configuración del servidor Mealie. La fragmentación de las respuestas es útil para mitigar el agotamiento de la memoria en el servidor Mealie; sin embargo, una sola solicitud a un archivo externo arbitrariamente grande (por ejemplo, una ISO de Debian) suele ser suficiente para saturar completamente un núcleo de CPU asignado al contenedor Mealie. Sin una limitación de velocidad, es posible no solo mantener el tráfico contra un objetivo externo indefinidamente, sino también agotar los recursos de CPU asignados al contenedor Mealie. Esta vulnerabilidad se solucionó en 1.4.0.
