CVE-2023-20007: Cisco Security Advisory: Cisco RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers Remote Code Execution and Denial of Service Vulnerability
A vulnerability in the web-based management interface of Cisco Small Business RV340, RV340W, RV345, and RV345P Dual WAN Gigabit VPN Routers could allow an authenticated, remote attacker to execute arbitrary code or cause the web-based management process on the device to restart unexpectedly, resulting in a denial of service (DoS) condition. The attacker must have valid administrator credentials. This vulnerability is due to insufficient validation of user-supplied input to the web-based management interface. An attacker could exploit this vulnerability by sending crafted HTTP input to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the web-based management process to restart, resulting in a DoS condition.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
