|CVSS SCORE||8.0, (AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)|
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of the Western Digital MyCloud PR4100 NAS device. Authentication is required to exploit this vulnerability.
The specific flaw exists within the REST SDK. The issue results from the lack of proper validation of a user-supplied string before passing it to the "call_user_function" inbuilt function. An attacker can leverage this vulnerability to execute code in the context of root.
Fixed in My Cloud Firmware Version 5.26.119
