Dragonfly hasta la versión 2.0.2 contiene una vulnerabilidad de asignación de memoria sin límites que permite a clientes no autenticados agotar la memoria pasando un COUNT negativo a HRANDFIELD, ZRANDMEMBER o SRANDMEMBER. Los atacantes pueden enviar un único comando contra una clave de un solo elemento con un COUNT negativo muy grande para activar el OOM killer, terminando la instancia para todos los clientes.

Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector AV:N/PR:N/UI:N: un solo comando con COUNT negativo agota la memoria y el OOM killer termina la instancia para todos los clientes, lo que encaja con DoS por agotamiento de recursos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
