A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, RV130 VPN Router, RV130W Wireless-N Multifunction VPN Router, and RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary commands with administrative commands on an affected device. The vulnerability is due to improper session management on affected devices. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected device. A successful exploit could allow the attacker to gain administrative access on the affected device. Cisco has released software updates that address the vulnerability described in this advisory. There are no workarounds that address this vulnerability.

This vulnerability affects all releases of the following Cisco products if they are running a vulnerable software release:
The web-based management interface of these devices is available through a local LAN connection or the remote management feature. By default, the remote management feature is disabled for these devices.
To determine whether the remote management feature is enabled for a device, administrators can open the web-based management interface and choose Basic Settings > Remote Management. If the Enable box is checked, remote management is enabled for the device.
Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability.
There are no workarounds that address this vulnerability. Disabling the remote management feature, if not required, would help to reduce the attack surface of this vulnerability.
Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/end-user-license-agreement.html
Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.
When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page, 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.
Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html
Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.
