What’s the root cause of the problem according to CERT-In?

The issue stems from the improper neutralisation of a special element in a binary which is known as rf test. As outlined by CERT-In, this flaw exposes a network service to unauthenticated command injection.

How to protect your device:

To tackle this urgent matter, CERT-In recommends taking prompt action by patching TP-Link software without delay. Moreover, users are strongly encouraged to take proactive steps to bolster the security of their Wi-Fi networks and fend off potential threats:

1. Make sure to keep your router’s firmware up to date by installing the latest security patches provided by the manufacturers.

2. Avoid potential exploitation by changing the default login credentials. Replace commonly used usernames and passwords with unique and strong ones.

3. Safeguard your data transmissions from interception by utilising WPA3 or WPA2 encryption protocols.

4. Minimise risks by turning off remote management features which could potentially be exploited by unauthorised parties.
