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.
