Title: Western Digital MyCloud NAS Devices Found to Contain Numerous Vulnerabilities
Description: Researchers have found that Western Digital MyCloud NAS devices contain numerous vulnerabilities that could be remotely exploited. One of the vulnerabilities disclosed is a login bypass vulnerability which could allow a remote attacker to login to these devices as an administrator. In addition to the login bypass flaw, many authenticated and unauthenticated remote command execution bugs have also been identified that allow a remote attacker to execute commands on the device as root (note that with the login bypass vulnerability, it’s possible for all the authenticated remote command execution flaws to be exploited). These vulnerabilities are considered zero-day vulnerabilities. Users and administrators should exercise caution and ensure these devices are NOT publically accessible.
