vulnerabilities:

  - 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 unauthenticated, remote attacker to execute arbitrary code on an affected
    device or cause the device to reload, resulting in a denial of service (DoS) condition. (CVE-2021-1609)

  - 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 commands with root
    privileges on an affected device. (CVE-2021-1610)

Please see the included Cisco BIDs and Cisco Security Advisory for more information.
