CWEs:            CWE-121


  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:

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.


  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.
