Security Gaps in TP-Link Devices Expose Users to Full Control Attacks

TP-Link has disclosed multiple serious security flaws in its Archer BE230 v1.2 Wi-Fi router. These vulnerabilities allow attackers with administrative access to run system commands and take complete control of the device.

Security researchers identified nine separate command injection issues affecting different parts of the router software, including web management, VPN services, cloud communication, and configuration features.

What’s the Core Problem?

The router firmware does not properly validate certain inputs. Because of this, attackers can inject malicious operating system commands through authenticated interfaces.

Most of the vulnerabilities require access from the local network with high privileges. However, one flaw can be triggered remotely by importing a specially crafted configuration file, increasing the risk.

What Could Happen?

If exploited, attackers could:

• Take full administrative control of the router
• Change network settings
• Intercept internet traffic
• Install backdoors for long-term access
• Move deeper into internal networks

This could affect both home users and organizations using the device.
