Summary
Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers Remote Code Execution Vulnerabilities
Notes
Summary
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV160, RV160W, RV260, RV260P, and RV260W VPN Routers could allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device.
These vulnerabilities exist because HTTP requests are not properly validated. An attacker could exploit these vulnerabilities by sending a crafted HTTP request to the web-based management interface of an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
This advisory is available at the following link:
https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv160-260-rce-XZeFkNHf ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv160-260-rce-XZeFkNHf"]
Vulnerable Products
These vulnerabilities affect the following Cisco Small Business Routers if they are running a firmware release earlier than Release 1.0.01.02:
RV160 VPN Router
RV160W Wireless-AC VPN Router
RV260 VPN Router
RV260P VPN Router with POE
RV260W Wireless-AC VPN Router
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this these vulnerabilities.
Cisco has confirmed that these vulnerabilities do not affect the following Cisco products:
RV340 Dual WAN Gigabit VPN Router
RV340W Dual WAN Gigabit Wireless-AC VPN Router
RV345 Dual WAN Gigabit VPN Router

Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has released free software updates that address the vulnerabilities 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 ["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 ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], 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 Without Service Contracts
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 ["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.
Fixed Releases
Cisco fixed these vulnerabilities in firmware releases 1.0.01.02 and later for Cisco RV160, RV160W, RV260, RV260P, and RV260W Routers.
To download the software from the Software Center ["https://software.cisco.com/download/"] on Cisco.com, do the following:
Click Browse all.
Choose Routers > Small Business Routers > Small Business RV Series Routers.
Choose the appropriate router.
Choose Small Business Router Firmware.
Choose a release from the left pane of the product page.
