Potential Risks

Exploitation of these vulnerabilities can lead to:

• Unauthorized Access: Attackers can gain administrative control over the router, allowing them to alter settings, monitor network traffic, and access connected devices.

• Malware Deployment: Compromised routers can be used to distribute malware to devices within the network.

• Data Interception: Sensitive information transmitted over the network can be intercepted and potentially misused.

Recommended Actions for Users

To mitigate the risks associated with these vulnerabilities, users are advised to:

1. Update Firmware: Ensure that the router's firmware is updated to the latest version provided by ASUS. Firmware updates often include patches for known vulnerabilities.

2. Disable Remote Management: If not required, disable remote management features to reduce exposure to potential attacks.

3. Change Default Credentials: Replace default usernames and passwords with strong, unique credentials to prevent unauthorized access.

4. Monitor Network Activity: Regularly review network logs for any unusual activity that may indicate a security breach.
