CVE-2017-16934

The web server on DBL DBLTek devices allows remote attackers to execute arbitrary OS commands by obtaining the admin password via a frame.html?content=/dev/mtdblock/5 request, and then using this password for the HTTP Basic Authentication needed for a change_password.csp request, which supports a "<%%25call system.exec:" string in the passwd parameter.
