Summary
Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Management Interface Command Injection Vulnerabilities
Notes
Summary
Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to inject arbitrary commands that are executed with root privileges.
The vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to a targeted device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on an affected device.
Cisco has not 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-rv-command-inject-LBdQ2KRN ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv-command-inject-LBdQ2KRN"]
Vulnerable Products
These vulnerabilities affect the following Cisco Small Business routers:
RV110W Wireless-N VPN Firewall
RV130 VPN Router
RV130W Wireless-N Multifunction VPN Router
RV215W Wireless-N VPN Router
The web-based management interface of these devices is available through a local LAN connection, which cannot be disabled, or through the WAN connection if the remote management feature is enabled. By default, the remote management feature is disabled for these devices.
Determine the Device Configuration
To determine whether the remote management feature is enabled for a device, 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.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by these vulnerabilities
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has not released and will not release software updates to address the vulnerabilities described in this advisory. The Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers have entered the end-of-life process. Customers are advised to refer to the end-of-life notices for these products:
End-of-Sale and End-of-Life Announcement for the Cisco Small Business RV Series Routers (selected models) ["https://www.cisco.com/c/en/us/products/collateral/routers/small-business-rv-series-routers/eos-eol-notice-c51-742771.pdf"]
Customers are encouraged to migrate to the Cisco Small Business RV132W, RV160, or RV160W Routers.
When considering a device migration, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page ["http://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution.
In all cases, customers should ensure that the new device will be sufficient for their network needs, that new devices contain sufficient memory, and that current hardware and software configurations will continue to be supported properly by the new product. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.
