Eighteen brands of security camera digital video recorders are vulnerable to an attack that would allow a hacker to remotely gain control of the devices to watch, copy, delete or alter video streams at will, as well as to use the machines as jumping-off points to access other computers behind a company’s firewall, according to tests by two security researchers. And 58,000 of the hackable video boxes, all of which use firmware provided by the Guangdong, China-based firm Ray Sharp, are accessible via the Internet. Early last week a hacker who uses the handle someLuser found that commands sent to a Swann DVR via port 9000 were accepted without any authentication. That trick would allow anyone to retrieve the login credentials for the DVR’s web-based control panel. To compound the problem, the DVRs automatically make themselves visible to external connections using a protocol known as Universal Plug And Play, (UPnP) which maps the devices’ location to any local router that has UPnP enabled — a common default setting. …Neither Ray Sharp nor any of the eighteen firms have yet released a firmware fix.
