CVSS: 8.8EPSS: 7%CPEs: 11EXPL: 0CVE-2022-22990 – Limited authentication bypass vulnerability on Western Digital My Cloud devices
https://notcve.org/view.php?id=CVE-2022-22990
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. Se ha detectado una vulnerabilidad de omisión de autenticación limitada que podría permitir a un atacante lograr una ejecución de código remota y escalar privilegios en los dispositivos My Cloud. Se ha abordado esta vulnerabilidad al cambiar la lógica de comprobación de los tokens de acceso y reescribiendo la lógica de las reglas en los scripts de PHP 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. • https://www.westerndigital.com/support/product-security/wdc-22002-my-cloud-os5-firmware-5-19-117 https://www.zerodayinitiative.com/advisories/ZDI-22-076 https://www.zerodayinitiative.com/advisories/ZDI-22-347 • CWE-287: Improper Authentication CWE-697: Incorrect Comparison •
