CVE-2016-9592

Estado: ModificadaMedia (4.3)—

openshift, en versiones anteriores a la 3.3.1.11, 3.2.1.23 y 3.4, es vulnerable a un error cuando un volumen fracasa a la hora de desasociarse. Esto provoca que la operación de borrado falle con un error "VolumeInUse". Como la operación de borrado se reintenta cada 30 segundos para cada volumen, esto podría conducir a un ataque de denegación de servicio (DoS), ya que el número de peticiones API que se envían al proveedor cloud excede el límite de tasa de la API.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
