Security News > 2020 > July > Critical Vulnerabilities Can Be Exploited to Hack Cisco Small Business Routers
Cisco on Wednesday released security advisories to inform customers of several critical vulnerabilities that can be exploited remotely to hack small business routers and firewalls that are no longer being sold.
One of the critical flaws, which is tracked as CVE-2020-3330 and has a CVSS score of 9.8, affects Cisco Small Business RV110W Wireless-N VPN firewalls and it allows a remote and unauthenticated attacker to take full control of a device by connecting to it using a default and static password.
The third critical security hole fixed by the company this week in small business routers is CVE-2020-3144, which can be exploited to bypass authentication and execute arbitrary commands with admin privileges by sending malicious HTTP requests to the device.
Cisco also informed customers this week about the availability of patches for high-severity vulnerabilities affecting its SD-WAN solutions and some small business routers.
There is no evidence that any of these vulnerabilities has been exploited in malicious attacks and none of them appears to have been publicly disclosed before Cisco released fixes.
