CVE-2024-7142

Disk data disclosure via incomplete encryption enablement

Published Jan 10, 2025 · Updated Jan 13, 2025

Missing disk encryption in Arista Networks CloudVision Appliance allows physically proximate attackers to read data from removed disks. The cva disk encryption enable command assigns the RAID controller security key but can leave virtual disks reporting Secured = NO, so their contents remain unencrypted. Physical access to a configured DCA-350E-CV and removal of a disk are required; attaching that disk to another system exposes its data without the passphrase.
