Descriptions

Dell PowerScale OneFS versions 8.1.0 – 9.1.0 contain a "use of SSH key past account expiration" vulnerability. A user on the network with the ISI_PRIV_AUTH_SSH RBAC privilege that has an expired account may potentially exploit this vulnerability, giving them access to the same things they had before account expiration. This may by a high privileged account and hence Dell recommends customers upgrade at the earliest opportunity.

Dell PowerScale OneFS versiones 8.1.0 - 9.1.0, contienen una vulnerabilidad de "use of SSH key past account expiration". Un usuario en la red con el privilegio ISI_PRIV_AUTH_SSH RBAC que presenta una cuenta caducada puede potencialmente explotar esta vulnerabilidad, dándole acceso a las mismas cosas que tenía antes de una caducidad de la cuenta. Esto puede deberse a una cuenta con muchos privilegios y, por lo tanto, Dell recomienda a los clientes que se actualicen lo antes posible
