Synopsis

The remote device is out of support and affected by multiple vulnerabilities.

Description

According to it's reported model number, the remote device is a Cisco Small Business Router model RV016, RV042, RV042G, RV082, RV320, or RV325. It is, therefore no longer supported and affected by multiple vulnerabilities:

- A vulnerability in the web-based management interface of Cisco Small Business Routers could allow an unauthenticated, remote attacker to bypass authentication on the affected device. This vulnerability is due to incorrect user input validation of incoming HTTP packets. An attacker could exploit this vulnerability by sending crafted requests to the web-based management interface. A successful exploit could allow the attacker to gain root privileges on the affected device. (CVE-2023-20025)

- A vulnerability in the web-based management interface of Cisco Small Business Routers could allow an authenticated, remote attacker to inject arbitrary commands on an affected device. This vulnerability is due to improper validation of user input fields within incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device with root-level privileges. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. (CVE-2023-20118, CVE-2023-20026)
