8 CVEs affecting Western Digital products, tracked from the National Vulnerability Database, with CVSS/EPSS scores and exploitation status.
Most Affected Products
Western Digital My Cloud Home before 3.6.0 and ibi before 3.6.0 allow Session Fixation.
Western Digital My Cloud EX2 Ultra firmware 2.31.195 allows a Buffer Overflow with Extended Instruction Pointer (EIP) control via crafted GET/POST parameters.
Western Digital My Cloud EX2 Ultra firmware 2.31.183 allows web users (including guest account) to remotely execute arbitrary code via a stack-based buffer overflow. There is no size verification logic in one of functions in libscheddl.so, and download_mgr.cgi makes it possible to enter large-sized f_idx inputs.
Western Digital My Cloud EX2 Ultra firmware 2.31.183 allows web users (including guest accounts) to remotely execute arbitrary code via a download_mgr.cgi stack-based buffer overflow.
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 unauthenticated file upload vulnerability. The page web/jquery/uploader/uploadify.php can be accessed without any credentials, and allows uploading arbitrary files to any location on the attached storage.
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.) It was found that it is possible for an unauthenticated attacker to create a valid session without a login. The network_mgr.cgi CGI module contains a command called "cgi_get_ipv6" that starts an admin session -- tied to the IP address of the user making the request -- if the additional parameter "flag" with the value "1" is provided. Subsequent invocation of commands that would normally require admin privileges now succeed if an attacker sets the username=admin cookie.
Unauthenticated Remote Command injection as root occurs in the Western Digital MyCloud NAS 2.11.142 /web/google_analytics.php URL via a modified arg parameter in the POST data.
