https://notcve.org/view.php?id=CVE-2020-28940
On Western Digital My Cloud OS 5 devices before 5.06.115, the NAS Admin dashboard has an authentication bypass vulnerability that could allow an unauthenticated user to execute privileged commands on the device. En los dispositivos Western Digital My Cloud OS 5 versiones anteriores a 5.06.115, el panel de administración de NAS presenta una vulnerabilidad de omisión de autenticación que podría permitir a un usuario no autenticado ejecutar comandos privilegiados en el dispositivo This vulnerability allows network-adjacent attackers to bypass authentication on affected installations of Western Digital MyCloud PR4100. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the nasAdmin service, which listens on TCP port 80 and 443 by default. The issue results from incorrect string matching logic when accessing protected pages. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. • https://support.wdc.com/downloads.aspx?g=907&lang=en#downloads https://www.westerndigital.com/support/productsecurity/wdc-20009-os5-firmware-5-06-115 https://www.zerodayinitiative.com/advisories/ZDI-20-1445 • CWE-287: Improper Authentication •
