Cisco SD-WAN Solution Certificate Validation Vulnerability
Priority: High
Advisory ID: cisco-sa-20180905-sd-wan-validation
First Published: 2018 September 5 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvi69940
CVE-2018-0434
CWE-295
CVSS Score: Base 8.1
CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:X/RL:X/RC:X
Summary
* A vulnerability in the Zero Touch Provisioning feature of the Cisco SD-WAN
Solution could allow an unauthenticated, remote attacker to gain
unauthorized access to sensitive data by using an invalid certificate.
The vulnerability is due to insufficient certificate validation by the
affected software. An attacker could exploit this vulnerability by
supplying a crafted certificate to an affected device. A successful exploit
could allow the attacker to conduct man-in-the-middle attacks to decrypt
confidential information on user connections to the affected software.
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-20180905-sd-wan-validation
Affected Products
* Vulnerable Products
This vulnerability affects the following Cisco products if they are running
a release of the Cisco SD-WAN Solution prior to Release 18.3.0:
+ vEdge 100 Series Routers
+ vEdge 1000 Series Routers
+ vEdge 2000 Series Routers
+ vEdge 5000 Series Routers
+ vManage Network Management System
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
Workarounds
* There are no workarounds that address this vulnerability.
Fixed Software
* 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.
