A vulnerability classified as problematic has been found in Western Digital My Cloud Home, My Cloud Home Duo and SanDisk ibi on Linux (Cloud Software). This affects some unknown functionality of the component HTTP API. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22.
