The Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, Cisco RV180W Wireless-N Multifunction VPN Router, and Cisco RV220W Wireless Network Security Firewall are easy-to-use, flexible, high-performance devices well suited for small businesses. They deliver highly secure, broadband, wired, and wireless connectivity to multiple offices and remote employees.
Cisco RV Series Routers Command Injection VulnerabilityA vulnerability in the network diagnostics administration pages of the Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, Cisco RV180W Wireless-N Multifunction VPN Router, and Cisco RV220W Wireless Network Security Firewall could allow an authenticated, remote attacker to execute arbitrary commands on the devices.
The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. An exploit could allow the attacker to execute arbitrary commands on the device with root privileges.
This vulnerability is documented in Cisco bug ID CSCuh87126 (registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2014-2177.
Cisco RV Series Routers HTTP Referer Header VulnerabilityA vulnerability in the administrative web interface of the Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, Cisco RV180W Wireless-N Multifunction VPN Router, and Cisco RV220W Wireless Network Security Firewall could allow an unauthenticated, remote attacker to perform a cross-site request forgery (CSRF) attack.
The vulnerability is due to insufficient CSRF protections. An attacker could exploit this vulnerability by persuading a user who is authenticated to the device to click a malicious link. An exploit could allow the attacker to perform actions in the administrative web pages of the device with the privileges of the authenticated user.
This vulnerability is documented in Cisco bug ID CSCuh87145 (registered customers only) and has been assigned CVE ID CVE-2014-2178.
Cisco RV Series Routers Insecure File Upload VulnerabilityA vulnerability in the file upload routines of the Cisco RV120W Wireless-N VPN Firewall, Cisco RV180 VPN Router, Cisco RV180W Wireless-N Multifunction VPN Router, and Cisco RV220W Wireless Network Security Firewall could allow an unauthenticated, remote attacker to upload files to arbitrary locations on the devices.
The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. An exploit could allow the attacker to upload files to an arbitrary location on the device.
This vulnerability is documented in Cisco bug ID CSCuh86998 (registered customers only) and has been assigned CVE ID CVE-2014-2179.

The following mitigations help limit the exposure to these vulnerabilities.
Disable Remote Management
Caution: Do not disable remote management if you manage the device via the WAN connection. This will result in loss of management connectivity to the device. Disabling this feature prevents Cisco QuickVPN access.
Remote Management is disabled by default. If it is enabled, administrators can disable it using the Web Access screen: Administration > Management Interface > Web Access. Check the box for Disabled in the Remote Management field.
Disabling remote management helps ensure that only users on the LAN could attempt to exploit the vulnerabilities.
Limit Remote Management Access to Specific IP Addresses
If remote management is required, harden the device so that it can be accessed only by certain IP addresses, rather than the default setting of any. By accessing the configuration screen (Administration > Management Interface > Web Access), an administrator can change the Remote IP address field to ensure only devices with the specified IP addresses can access the device.

When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Notices archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
