Critical security vulnerabilities in Cisco's Small Business RV Series routers could allow privilege escalation, remote code execution with root privileges on the devices and more.
The critical bugs are part of 15 total vulnerabilities affecting the RV product line that Cisco disclosed this week.
The flaws tracked as CVE-2022-20700, CVE-2022-20701 and CVE-2022-20702 meanwhile exist in the web-based management interface of Cisco Small Business RV Series Routers and could allow a remote attacker to elevate privileges to root.
Three bugs affecting the RV340, RV340W, RV345 and RV345P Dual WAN Gigabit VPN routers could allow an unauthenticated, remote attacker to inject and execute arbitrary commands on the underlying Linux operating system, Cisco warned.
A vulnerability in the Open Plug and Play module of the appliances could allow an unauthenticated, remote attacker to inject and execute arbitrary commands on the underlying Linux operating system, Cisco said.
