      "value": "EMQX is a scalable and reliable MQTT broker for AI, IoT, IIoT, and connected vehicles. Prior to versions 5.8.11, 5.9.3, 5.10.4, 6.0.3, 6.1.2, and 6.2.1, the plugin-install REST API and dashboard upload accepted stale grants created with emqx ctl plugins allow because there was no five-minute grant lifetime or SHA-256 package binding. An attacker with a compromised dashboard administrator credential or API key with plugin-install permission who finds a stale allowed name and version can upload attacker-controlled bytes under the allowed .tar.gz filename through POST /api/v5/plugins/install or the dashboard plugin upload. The broker then installs and runs attacker-controlled Erlang code with the privileges of the EMQX process. This issue is fixed in versions 5.8.11, 5.9.3, 5.10.4, 6.0.3, 6.1.2, and 6.2.1."

Antes de las versiones 5.8.11, 5.9.3, 5.10.4, 6.0.3, 6.1.2 y 6.2.1, la API REST de instalación de plugins y la carga del panel de control aceptaban permisos caducados creados con emqx ctl plugins allow porque no había una vida útil de permiso de cinco minutos o una vinculación de paquete SHA-256. Un atacante con una credencial de administrador del panel de control comprometida o una clave API con permiso de instalación de plugins que encuentre un nombre y versión permitidos caducados puede cargar bytes controlados por el atacante bajo el nombre de archivo .tar.gz permitido a través de POST /api/v5/plugins/install o la carga de plugins del panel de control. El broker entonces instala y ejecuta código Erlang controlado por el atacante con los privilegios del proceso EMQX. Este problema está solucionado en las versiones 5.8.11, 5.9.3, 5.10.4, 6.0.3, 6.1.2 y 6.2.1."
