CVE-2022-20700 Small Business RV160, RV260, RV340, and RV345 routers could be exploited by an attacker to execute arbitrary code, elevate privileges, or bypass authentication and authorization.

CVE-2022-20700 Small Business RV160, RV260, RV340, and RV345 routers could be exploited by an attacker to execute arbitrary code, elevate privileges, or bypass authentication and authorization.

Cisco Small Business RV Series Routers running Cisco IOS Software could allow an attacker to exploit multiple vulnerabilities to execute arbitrary code, elevate privileges, bypass authentication and authorization, and cause a denial of service (DoS) to the device. Cisco has released software updates that address these vulnerabilities. There are no workarounds. However, you can mitigate these vulnerabilities by configuring basic security best practices, such as anti-virus, firewall, and intrusion detection/prevention measures.

Overview of the Vulnerabilities

Cisco Small Business RV Series Routers running Cisco IOS Software could allow an attacker to exploit multiple vulnerabilities to execute arbitrary code, elevate privileges, bypass authentication and authorization, and cause a denial of service (DoS) to the device. The vulnerabilities are due to multiple errors in the Cisco IOS Software including improper input validation and buffer overflow conditions. These vulnerabilities may be exploited by sending crafted packets on an affected system. They may also be exploited remotely via exploitation of other vulnerabilities or as non-authenticated remote access with default user credentials. An attacker's actions can result in a DoS condition as well as unauthorized remote access to the device.

Multiple Cisco Small Business RV Series Routers running Cisco IOS Software could be exploited due to multiple vulnerabilities. Cisco has released software updates that address these vulnerabilities. There are no workarounds. However, you can mitigate these vulnerabilities by configuring basic security best practices, such as anti-virus, firewall, and intrusion detection/prevention measures.
