https://notcve.org/view.php?id=CVE-2019-9950
Western Digital My Cloud, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 and My Cloud PR4100 firmware before 2.31.174 is affected by an authentication bypass vulnerability. The login_mgr.cgi file checks credentials against /etc/shadow. However, the "nobody" account (which can be used to access the control panel API as a low-privilege logged-in user) has a default empty password, allowing an attacker to modify the My Cloud EX2 Ultra web page source code and obtain access to the My Cloud as a non-Admin My Cloud device user. My Digital, My Cloud Mirror Gen2, My Cloud EX2 Ultra, My Cloud EX2100, My Cloud EX4100, My Cloud DL2100, My Cloud DL4100, My Cloud PR2100 y My Cloud PR4100 firmware anterior a 2.31.174, se ve impactado por una vulnerabilidad de omisión de autenticación . El archivo login_mgr.cgi verifica las credenciales contra /etc/shadow. • https://bnbdr.github.io/posts/wd https://community.wd.com/t/new-release-my-cloud-firmware-versions-2-31-174-3-26-19/235932 https://github.com/bnbdr/wd-rce https://support.wdc.com/downloads.aspx?g=2702&lang=en • CWE-521: Weak Password Requirements •
CVE-2018-17153 – Western Digital MyCloud Unauthenticated Command Injection
https://notcve.org/view.php?id=CVE-2018-17153
It was discovered that the Western Digital My Cloud device before 2.30.196 is affected by an authentication bypass vulnerability. An unauthenticated attacker can exploit this vulnerability to authenticate as an admin user without needing to provide a password, thereby gaining full control of the device. (Whenever an admin logs into My Cloud, a server-side session is created that is bound to the user's IP address. After the session is created, it is possible to call authenticated CGI modules by sending the cookie username=admin in the HTTP request. The invoked CGI will check if a valid session is present and bound to the user's IP address.) • http://packetstormsecurity.com/files/173802/Western-Digital-MyCloud-Unauthenticated-Command-Injection.html http://www.securityfocus.com/bid/105359 https://securify.nl/nl/advisory/SFY20180102/authentication-bypass-vulnerability-in-western-digital-my-cloud-allows-escalation-to-admin-privileges.html https://support.wdc.com/knowledgebase/answer.aspx?ID=25952 https://www.securify.nl/advisory/authentication-bypass-vulnerability-in-western-digital-my-cloud-allows-escalation-to-admin-privileges https://web.archive.org/web/20170315123948/https • CWE-287: Improper Authentication •
