Summary dbcve.org

Multiple critical vulnerabilities in Cisco Small Business RV series routers (RV160, RV260, RV340, RV345) allow remote attackers to execute arbitrary code, elevate privileges, run arbitrary commands, bypass authentication/authorization controls, fetch and execute unsigned software, and cause denial of service. The CVSS 9.8 score indicates likely unauthenticated, network-exploitable vulnerabilities with complete system compromise potential.

Mitigation

Apply Cisco-provided firmware updates for the affected router models. Prioritize patching given the critical severity and wide range of exploitation possibilities including authentication bypass and arbitrary code execution.
