The vulnerability exists because the affected software has user accounts with default, static passwords. An attacker with access to the NFVIS CLI of an affected device could exploit this vulnerability by logging into the CLI. A successful exploit could allow the attacker to access the NFVIS CLI with administrator privileges. 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-waas-encsw-cspw-cred-hZzL29A7 Affected Products o Vulnerable Products This vulnerability affects Cisco ENCS 5400-W Series and CSP 5000-W Series appliances if they are running Cisco vWAAS with NFVIS-bundled image releases 6.4.5, or 6.4.3d and earlier. Products Confirmed Not Vulnerable Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability. Cisco has confirmed that this vulnerability does not affect standalone NFVIS running on Cisco ENCS 5000 Series and Cisco CSP 5000 Series devices, and it does not affect standalone vWAAS software or WAAS software running on Cisco Wide Area Virtualization Engine (WAVE) appliances. Details o In order to exploit this vulnerability, an attacker would need to be able to connect to the NFVIS CLI on an affected device. This would require access to one of the following: The Ethernet management port for the CPU on an affected ENCS 5400-W Series appliance. This interface might be remotely accessible if a routed IP is configured. The first port on the four-port I350 PCIe Ethernet Adapter card on an affected CSP 5000-W Series appliance. This interface might be remotely accessible if a routed IP is configured. A connection to the vWAAS software CLI and a valid user credential to authenticate on the vWAAS CLI first. A connection to the Cisco Integrated Management Controller (CIMC) interface of the ENCS 5400-W Series or CSP 5000-W Series appliance and a valid user credential to authenticate to the CIMC first. 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 Cisco vWAAS with NFVIS-bundled image release 6.4.3e, 6.4.5a, and later releases. Note : ENCS 5400-W Series and CSP 5000-W Series appliances do not support a direct upgrade to vWAAS 6.4.3e and 6.4.5a releases from earlier releases. In order to run a fixed release, customers must do a fresh install with the required version of the Cisco WAAS Unified Package for ENCS 5400-W and CSP 5000-W appliances. Customers are advised to contact their support organization for any assistance required with migrating to a fixed release. To download the software from the Software Center on Cisco.com , do the following: 1. Click Browse all . 2. Choose Routers > Wan Optimization > Wide Area Application Services (WAAS) Software > Wide Area Application Services (WAAS) Software . 3.
