Description
An authenticated, low-privileged user with access to the NetBackup Flex
OS management shell could supply a specially crafted input to a
privileged administrative command, causing it to execute arbitrary code
with root-level permissions. Successful exploitation grants the attacker
unrestricted control over the Flex appliance host and all hosted
containers, fully compromising confidentiality, integrity, and
availability.
