Cisco RV110W, RV130W, and RV215W Routers Management Interface Denial of Service
Vulnerability
Priority: High
Advisory ID: cisco-sa-20190619-rvrouters-dos
First Published: 2019 June 19 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds availableCisco Bug IDs: CSCvo21850CSCvo39082CSCvo39087
CVE-2019-1843
CWE-20
CVSS Score:
8.6 AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:X/RL:X/RC:X
Summary
o A vulnerability in the web-based management interface of the Cisco RV110W
Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router,
and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated,
remote attacker to cause a reload of an affected device, resulting in a
denial of service (DoS) condition.
This vulnerability is due to improper validation of user-supplied data in
the web-based management interface. An attacker could exploit this
vulnerability by sending malicious HTTP requests to a targeted device. A
successful exploit could allow the attacker to reload the device and
causing a DoS condition.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/
cisco-sa-20190619-rvrouters-dos
Affected Products
o Vulnerable Products
This vulnerability affects all releases of the following Cisco products
prior to those listed in Fixed Releases :
RV110W Wireless-N VPN Firewall
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 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.
Determining the Small Business Router Firmware Release
To determine the installed release of the Small Business Router Firmware,
administrators can log in to the web-based management interface and click
the About link in the upper right corner. A pop-up window will appear
containing information about the currently installed Small Business Router
Firmware.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Workarounds
o There are no workarounds that address this vulnerability.
Fixed Software
o 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 and Alerts 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 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
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.
