Summary

  o A vulnerability in the web-based management interface of Cisco Small
    Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an
    unauthenticated, remote attacker to retrieve sensitive information.

    The vulnerability is due to improper access controls for URLs. An attacker
    could exploit this vulnerability by connecting to an affected device via
    HTTP or HTTPS and requesting specific URLs. A successful exploit could
    allow the attacker to download the router configuration or detailed
    diagnostic information.

    Cisco has released firmware 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-20190123-rv-info

Affected Products

  o Vulnerable Products

    This vulnerability affects Cisco Small Business RV320 and RV325 Dual
    Gigabit WAN VPN Routers running Firmware Releases 1.4.2.15 and 1.4.2.17.

    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.

    Fixed Releases

    Cisco fixed this vulnerability in RV320 and RV325 Dual Gigabit WAN VPN
    Routers Firmware Releases 1.4.2.19 and later.

    Customers can download the software from the Software Center on Cisco.com
    by doing the following:

     1. Click Browse all.
     2. Navigate to Routers > Small Business Routers > Small Business RV Series

Summary

  o A vulnerability in the web-based management interface of Cisco Small
    Business RV320 and RV325 Dual Gigabit WAN VPN Routers could allow an
    authenticated, remote attacker with administrative privileges on an
