Summary dbcve.org
Multiple critical vulnerabilities in Cisco Small Business RV Series Routers (RV160, RV260, RV340, RV345) allow attackers to execute arbitrary code, elevate privileges, run arbitrary commands, bypass authentication/authorization, fetch/run unsigned software, and cause denial of service. These are likely command injection, authentication bypass, and firmware integrity validation flaws in the router firmware.
Mitigation
Apply Cisco's available firmware updates for the affected router series; until patched, restrict management interface access to trusted networks and monitor for unauthorized access attempts.
