The Houston Chronicle explains how this could become a widespread problem: An individual with nefarious intent can repeatedly reset the modem, bringing the user offline again and again. Rebooting the modem will disrupt your Internet connection for under a minute, but doing a factory reset could bring the modem offline until someone reaches the cable company to request the modem be reauthorized. In addition to technical information about the modem and the cable system’s current cable broadband configuration, there are two user accessible reset buttons, one to reboot the modem and another to reset it to its original factory settings. If you own or lease a Motorola/Arris SurfBoard 5100, 6121, or 6141 cable modem, security researchers have uncovered an annoying vulnerability that could expose you to a denial of service attack.ĭavid Longenecker first discovered the flaw with the world’s most popular cable modem - the SB-6141, a highly recommended DOCSIS 3 model. The firmware does not password protect access to the cable modem’s configuration menu, accessible by visiting 192.168.100.1 in a web browser. ![]() Phillip Dampier ApConsumer News 1 Comment
