Summary
Cisco SD-WAN vEdge Routers Denial of Service Vulnerability
Notes
Summary
A vulnerability in the deep packet inspection (DPI) engine of Cisco SD-WAN vEdge Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
The vulnerability is due to improper processing of FTP traffic. An attacker could exploit this vulnerability by sending crafted FTP packets through an affected device. A successful exploit could allow the attacker to make the device reboot continuously, causing a DoS condition.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
Vulnerable Products
This vulnerability affects the following software releases for Cisco SD-WAN vEdge 5000 Series Routers and Cisco SD-WAN vEdge Cloud Router if they have the DPI feature enabled:
19.2.0
19.2.097
19.2.098
19.2.1
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by this vulnerability.
Cisco has confirmed that this vulnerability does not affect releases 18.4 or earlier of Cisco SD-WAN vEdge 5000 Series Routers or Cisco SD-WAN vEdge Cloud Router.
Cisco has also confirmed that this vulnerability does not affect the following Cisco products:
IOS XE SD-WAN Software
SD-WAN cEdge Routers
SD-WAN vBond Orchestrator Software
SD-WAN vEdge 100 Series Routers
SD-WAN vEdge 1000 Series Routers
SD-WAN vEdge 2000 Series Routers
SD-WAN vManage Software
SD-WAN vSmart Controller Software
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 ["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 ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], 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 ["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
Customers are advised to upgrade to an appropriate fixed software release as indicated in the following table(s). To ensure a complete upgrade solution, consider that this advisory is part of a collection that includes the following advisories:
