Description

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an authenticated, remote attacker to inject and execute arbitrary commands on the underlying operating system of an affected device. These vulnerabilities are due to insufficient validation of user-supplied input. An attacker could exploit these vulnerabilities by sending malicious input to an affected device. A successful exploit could allow the attacker to execute arbitrary commands as the root user on the underlying Linux operating system of the affected device. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates to address these vulnerabilities.
