26 Aug Hackers Exploit Vulnerability Targeting Routers and Modems Running Arcadyan Firmware
Almost immediately after being disclosed publicly, a vulnerability with routers running Arcadyan firmware has been exploited by hackers, potentially affecting millions of home routers.
Although this vulnerability was disclosed to router manufacturers in April, it was made public on August 3. There have been reports of hackers actively attacking these compromised routers since.
What is the issue?
The vulnerability, referred to as CVE-2021-20090, is a critical path traversal vulnerability in the web interfaces of routers with Arcadyan firmware. The vulnerability allows remote attackers to bypass authentication. This makes it possible for attackers to deploy Mirai botnet malicious payloads to affected devices.
Why should I be concerned?
This vulnerability can allow an unauthenticated remote attacker to take control of connected devices. Once this happens, the attacker can:
- Manipulate your internet traffic
- Gain access to sensitive information on your devices
- Alter router settings to make your network more vulnerable
Because not a lot of people are even aware of this security risk and people do not change their routers very frequently, this vulnerability presents a very serious problem for many.
