Description

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV160 RV160W RV260 RV260P and RV260W VPN Routers could allow an unauthenticated remote attacker to conduct directory traversal attacks and overwrite certain files that should be restricted on an affected system. These vulnerabilities are due to insufficient input validation.
