Executive brief
Dell PowerProtect Data Domain is a backup and storage solution used to protect and manage corporate data. A security flaw in the system's authorization checks could allow a user with low-level access to gain unauthorized permissions. This could lead to the exposure of sensitive data or unauthorized changes to the storage environment.
