Description
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability was discovered via an HTTP API on Western Digital My Cloud Home; My Cloud Home Duo; and SanDisk ibi devices that could allow an attacker to abuse certain parameters to point to random locations on the file system.
