Executive brief
Quest NetVault Backup is a data protection solution used to back up and restore enterprise data across physical and virtual environments. A security flaw in its removable media management component allows a remote attacker to bypass authentication and execute unauthorized commands on the server. This could lead to a total compromise of the backup system, potentially resulting in the loss, theft, or encryption of critical business data.
Technical details
