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 •
