My old HP laptop with Windows XP runs free version installed in November 2018. I installed the latest free version of Avast on my Windows 10 desktop. Avast does not show it, however, it can be determined by Rogers technician. I don't know what is the firmware version on them. Both modems use original factory settings. I did not make any changes to the DNS servers on the first and the second (current) Hitron CODA-4582U modem. The latest version of Hitron CODA-4582U modem firmware presumably should have it. Please help to resolve this problem that was detected first time by Google security team back in September 2017.īTW, a new security patch in modems' firmware was created and released by Red Hat in October 2017. All modem settings were verified by Rogers' technical support and they were all OK. You may google this ID to get more details about this critical security issue.Īny attempts to reboot Hitron modem, reset to the factory settings, replace it with the new one and even installing the latest version of Avast antivirus on both Windows PCs did not help. However, starting January 14 Avast started indicating this home network security problem:ĭNS: Device is vulnerable to attacks - vulnerability ID: CVE-2017-14491.Īttackers can abuse this vulnerability to disrupt normal functions of this device and make it unresponsive.Īttackers can execute their own code on this device. When I ran antivirus just after the upgrade no network security problems were detected. On January 11, 2019, I upgraded my internet service to Ignite500 and had to replace my old Hitron modem with the brand new one Hitron CODA4582. There were no Avast updates during the past few weeks. Avast antivirus was running on two my Windows PC and never detected an issue with my home network. I had no network security problems during the past several years using Ignite30 internet service.
