The Cisco Small Business RV Series Router is a popular networking device used mainly by small businesses to provide secure and reliable access to the internet. These dual Gigabit WAN VPN routers provide high-performance connectivity and advanced security features for small businesses and home offices. They offer multiple WAN connections with load balancing and failover, VPN support, and a web-based management interface for easy configuration and management.
However, a serious vulnerability, identified as CVE-2019-1653, has been detected in these routers, which could allow an unauthenticated attacker to retrieve sensitive information from the web-based management interface. This vulnerability is due to improper access controls for URLs and can be exploited by connecting to an affected device via HTTP or HTTPS and requesting specific URLs.
If this vulnerability is exploited, an attacker can easily retrieve the router configuration or detailed diagnostic information. This sensitive information can be used to further compromise the network, steal valuable data, or launch other malicious attacks.
