Wireless Router Security: CVE-2023-43130 and CVE-2023-4312 on D-LINK DIR-806 1200M11AC
Nowadays, wireless routers have become an essential part of our homes and workplaces. These devices allow us to distribute our internet connection and connect our wireless devices. However, vulnerabilities can compromise your wireless routers and make your information vulnerable to attacks. In this article, we will focus on two important vulnerabilities on the D-LINK DIR-806 1200M11AC wireless router: CVE-2023-43130 and CVE-2023-43129.
CVE-2023-43130: Command Injection
CVE-2023-43130 is a vulnerability in the DIR-806 1200M11AC wireless router that causes command injection. This vulnerability allows attackers to inject malicious commands into the router. Hence, attackers can hijack your router and take control of it. This can compromise your sensitive information and seriously compromise your network security.
CVE-2023-43129: Command Injection (Inadequate Filtering of REMOTE_PORT Parameters)
CVE-2023-43129 is a vulnerability found in the same router model. This vulnerability relies on inadequate filtering of incoming REMOTE_PORT parameters by the router. Attackers can use this vulnerability to transmit malicious commands through these parameters. As a result, the router may accept these malicious commands and cause damage to the operating system. This poses a major threat to network security.
These vulnerabilities show that users need to keep their wireless routers secure. Here are some important steps you should consider:
Follow Firmware Updates: The manufacturer regularly releases firmware updates to fix security vulnerabilities. Follow these updates regularly and keep your router updated.
Use Strong Passwords: Change the router admin password and make it harder for attackers to access by using a complex password.
Disable Remote Access: If you do not require remote access to the router, disable this feature. This reduces the potential attack surface.
Enable Firewall: Keep incoming and outgoing traffic under control by enabling your router's built-in firewall.
Identify Your Trusted Devices: Allow only trusted devices to connect to your network using MAC address filtering.
Wireless router security is critical to keeping internet users and their networks safe. Closing these vulnerabilities and keeping your device updated will make your online experience safer.
