CWEs: CWE-121
Summary
o 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 execute arbitrary code or cause an
affected device to restart unexpectedly.
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 an affected device. A
successful exploit could allow the attacker to execute arbitrary code as
the root user on the underlying operating system or cause the device to
reload, resulting in a denial of service (DoS) condition. To exploit these
vulnerabilities, an attacker would need to have valid administrator
credentials on the 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://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-rv-overflow-WUnUgv4U
Affected Products
o 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 section of this advisory
are known to be affected by these vulnerabilities.
Workarounds
o There are no workarounds that address these vulnerabilities.
Fixed Software
o 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)
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 , to determine exposure and a
complete upgrade solution.
In all cases, customers should ensure that new device will be sufficient
for their network needs; new devices contain sufficient memory, and 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.
Exploitation and Public Announcements
o The Cisco Product Security Incident Response Team (PSIRT) is not aware of
any public announcements or malicious use of the vulnerabilities described
in this advisory.
