Title: Cisco VPN routers open to remote attacks
Description: Cisco disclosed multiple vulnerabilities in some of its RV series routers designed for use as small business VPNs. An adversary could exploit any of these flaws to view or manipulate data on the targeted device and perform other unauthorized actions. These routers have a VPN function built into them and are purpose-built for small and medium-sized businesses or as a way for users to access their office's network remotely. The vulnerabilities exist in the way the routers validate HTTP requests in its management interface. An attacker could exploit these vulnerabilities by sending a specially crafted HTTP request to the targeted device and then gain the ability to execute arbitrary code as a root user.
