Descriptions

A vulnerability in Cisco HyperFlex Software could allow an unauthenticated, remote attacker to generate valid, signed session tokens. The vulnerability is due to a static signing key that is present in all Cisco HyperFlex systems. An attacker could exploit this vulnerability by accessing the static signing key from one HyperFlex system and using it to generate valid, signed session tokens for another HyperFlex system. A successful exploit could allow the attacker to access the HyperFlex Web UI of a system for which they are not authorized.

Una vulnerabilidad en Cisco HyperFlex Software podría permitir que un atacante remoto no autenticado genere tokens de sesión válidos y firmados. La vulnerabilidad se debe a una clave de firma estática presente en todos los sistemas Cisco HyperFlex. Un atacante podría explotar esta vulnerabilidad accediendo a la clave de firma estática de un sistema HyperFlex y empleándolo para generar tokens de sesión firmados válidos para otro sistema HyperFlex. Su explotación con éxito podría permitir que el atacante acceda a la interfaz de usuario web de HyperFlex para el cual no está autorizado.
