ASUS released a security update for some of his routerrecommending users to install the latest firmware available for your device. The corrections concern three vulnerabilitiesidentified with the identifiers CVE-2026-75775, CVE-2026-75779 and CVE-2026-93489, which affect products belonging to the firmware families indicated by the company. The flaws are indicated with criticality “High“.
The advisory was published on October 23 and specifically affects certain routers using the 3.0.0.6_102 firmware branch. The presence of an authentication vulnerability is the most relevant aspect: under specific conditions, an unauthenticated attacker connected to an adjacent network can gain administrative access to the router, without having the normal access credentials.
The risk does not concern all company devices without distinction: it is necessary to check the model you own and the relevant firmware version. Unauthorized administrative access can allow you to change router settings and compromise the security of the network to which computers, smartphones, and other devices are connected.
How to secure your ASUS router
The main measure is to install the updated firmware intended for your model. The correct package can be found through the official ASUS support page or by consulting the manufacturer’s security bulletin.
Those who cannot immediately update their device should take some precautions:
- Disable remote access to router management from the WAN, if not necessary, to reduce the possibility of external access.
- Use strong, unique passwords for router administration and your Wi-Fi network.
- Restrict access to trusted devices and networks by controlling remote management settings.
- Check the connected devices and active sessions, deleting those that are unknown or no longer used.
Once the update is complete, it is recommended that you restart your router. During the firmware installation, however, you do not need to turn off the device. Procedures may vary depending on the model and interface used.
