Vulnerability from variot
A limited authentication bypass vulnerability was discovered that could allow an attacker to achieve remote code execution and escalate privileges on the My Cloud devices. Addressed this vulnerability by changing access token validation logic and rewriting rule logic on PHP scripts. My Cloud There is an authentication vulnerability in the device.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Western Digital MyCloud PR4100. Authentication is not required to exploit this vulnerability.The specific flaw exists within the nasAdmin service, which listens on TCP ports 80 and 443 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to bypass authentication on the system. Western Digital My Cloud is a personal cloud storage device from Western Digital
