AVG Network Inspector alert: Rom-0 vulnerability found

This article explains how to resolve the issue if Network Inspector in AVG AntiVirus shows the following alert:

  • Rom-0 vulnerability found

If you see the alert above after running a Network Inspector scan, your router contains a serious vulnerability that could allow an attacker to steal private data stored on your router, including the router's admin password. This password can be used to take control of your network, making all of the devices that are connected to your network vulnerable.

Solution

We recommend trying the possible solutions below in order:

Disable remote admin for your router

You can minimize the risks linked with this vulnerability by ensuring that the remote administration option in your router settings is disabled.

For instructions, refer to the Disable remote admin tab in the following article:

It is also necessary to update your router's firmware.

Disabling the remote administration option makes it more difficult for attackers to target your network, but does not resolve the issue. Network Inspector will continue to show the Rom-0 vulnerability found alert until you update your router's firmware.

Update your router's firmware

Newer versions of your router's firmware may contain a fix for this issue. Routers do not typically run updates automatically, so you need to manually download and install any available updates.

Consult the documentation for your router model for instructions on how to download and install firmware updates. If updated firmware is not available, contact the manufacturer of your router to request that they provide a firmware update as soon as possible.

Incorrectly applying firmware updates can make your router unusable. For this reason, it is essential to follow the exact instructions provided in your router's documentation. If you are unsure, contact your router manufacturer directly for further assistance.

Below are links to the support pages for common router brands:

Apple | Asus | AT&T | Belkin | Cisco | Dell | D-Link | DrayTek | Eero | GL.iNET | Google | Huawei | Linksys | MicroTik | Motorola | NEC | NETGEAR | Sagem/Sagemcom | Speedefy | TP-Link | TRENDnet | Ubiquiti | UniFi | Vodafone | Zyxel

If you are unable to install a firmware update, we recommend replacing your router.

Further details

Your router contains the ROM-0 backup disclosure vulnerability.
