Hackers Exploiting Cisco RV VPN Routers
Security researchers have found critical vulnerabilities in Cisco Small Business RV VPN routers. The bugs could allow attackers to take control of the router with root privileges, get access to customer data, and conduct DDOS attacks.
Why are they even still used? Well, the RV series of VPN appliances is affordable and functional. They can easily connect remote workers to a company network with no hassle. Each appliance has a built-in firewall, VPN, encryption, and authentication features.
Cisco disclosed 15 vulnerabilities affecting their RV product line this week. Some of the bugs can be exploited alone, but others can be chained together to lead to a variety of bad outcomes. These issues remain unpatched at the time of writing.
According to Cisco, the bugs affect products that the company makes. Cisco’s advisory said: “An attacker could exploit these vulnerabilities by sending malicious packets to the affected systems.”
