Message-ID: <ed8d7591-f4fa-6655-96e7-0c6a68d9d04c@securify.nl> Date: Tue, 7 Mar 2017 10:41:14 +0100 From: "Securify B.V." <lists@...urify.nl> To: fulldisclosure@...lists.org Subject: [FD] Western Digital My Cloud vulnerable to multiple command injection vulnerabilities ------------------------------------------------------------------------ Western Digital My Cloud vulnerable to multiple command injection vulnerabilities ------------------------------------------------------------------------ Remco Vermeulen, January 2017 ------------------------------------------------------------------------ Abstract ------------------------------------------------------------------------ It was discovered that the Western Digital My Cloud is affected by multiple command injection vulnerabilities. Some of these issues don't require authentication and allow an attacker to gain complete control (root access) of the affected device. Some do require authentication, in this case an attacker can use Cross-Site Request Forgery (CSRF, see advisory SFY20170104) or authentication bypass (see advisory SFY20170102) and still gain complete control of the vulnerable Western Digital device. ------------------------------------------------------------------------ See also ------------------------------------------------------------------------ - https://security.szurek.pl/wd-my-cloud-mirror-211153-rce-and-authentication-bypass.html - https://blog.exploitee.rs/2017/hacking_wd_mycloud/ - https://www.exploitee.rs/index.php/Western_Digital_MyCloud - https://securify.nl/advisory/SFY20170102/authentication_bypass_vulnerability_in_western_digital_my_cloud.html - https://securify.nl/advisory/SFY20170104/western_digital_my_cloud_vulnerable_to_cross_site_request_forgery_vulnerability.html ------------------------------------------------------------------------ Tested versions ------------------------------------------------------------------------ These vulnerabilities were successfully verified on a Western Digital My Cloud model WDBCTL0020HWT running firmware versions 2.21.119 and 2.21.126. These issues aren't limited to the model that was used to find these vulnerabilities since most of the products in the My Cloud series share the same (vulnerable) code. ------------------------------------------------------------------------ Fix ------------------------------------------------------------------------ There is currently no fix available. ------------------------------------------------------------------------ Details ------------------------------------------------------------------------ https://www.securify.nl/advisory/SFY20170103/western_digital_my_cloud_vulnerable_to_multiple_command_injection_vulnerabilities.html _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
