Western Digital WD Cloud

An uncontrolled resource consumption vulnerability issue that could arise by sending crafted requests to a service to consume a large amount of memory, eventually resulting in the service being stopped and restarted was discovered in Western Digital My Cloud Home, My Cloud Home Duo, SanDisk ibi and Western Digital My Cloud OS 5 devices. This issue requires the attacker to already have root privileges in order to exploit this vulnerability. This issue affects My Cloud Home and My Cloud Home Duo: before 9.5.1-104; ibi: before 9.5.1-104; My Cloud OS 5: before 5.27.161.

Server-side request forgery (SSRF) vulnerability that could allow a rogue server on the local network to modify its URL using another DNS address to point back to the loopback adapter. This could then allow the URL to exploit other vulnerabilities on the local server. This was addressed by fixing DNS addresses that refer to loopback. This issue affects My Cloud OS 5 devices before 5.27.161, My Cloud Home, My Cloud Home Duo and SanDisk ibi devices before 9.5.1-104.

Post-authentication remote command injection vulnerability in Western Digital My Cloud OS 5 devices that could allow an attacker to execute code in the context of the root user on vulnerable CGI files. This vulnerability can only be exploited over the network and the attacker must already have admin/root privileges to carry out the exploit. An authentication bypass is required for this exploit, thereby making it more complex. The attack may not require user interaction. Since an attacker must already be authenticated, the confidentiality impact is low while the integrity and availability impact is high.  This issue affects My Cloud OS 5 devices: before 5.26.300.
