Summary
Cisco IOS XE SD-WAN Software Parameter Injection Vulnerabilities
Notes
Summary
Multiple vulnerabilities in the CLI of Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to access the underlying operating system with root privileges.
These vulnerabilities are due to insufficient input validation of certain CLI commands. An attacker could exploit these vulnerabilities by authenticating to the device and submitting crafted input to the CLI. The attacker must be authenticated as an administrative user to execute the affected commands. A successful exploit could allow the attacker to access the underlying operating system with root privileges.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
Vulnerable Products
At the time of publication, these vulnerabilities affected universal Cisco IOS XE Software earlier than the first fixed release if it was running in Controller mode.
At the time of publication, these vulnerabilities affected all standalone Cisco IOS XE SD-WAN Software releases.
Note: The standalone Cisco IOS XE SD-WAN Software release images are separate from the universal Cisco IOS XE Software releases. The SD-WAN feature set was first integrated into the universal Cisco IOS XE Software releases starting with Cisco IOS XE Software Release 17.2.1r. For additional information, see the Install and Upgrade Cisco IOS XE Release 17.2.1r and Later ["https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/install-upgrade-17-2-later.html"] chapter of the Cisco SD-WAN Getting Started Guide.
For additional information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
See the Details section in the bug ID(s) at the top of this advisory for the most complete and current information.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by these vulnerabilities.
Cisco has confirmed that these vulnerabilities do not affect the following Cisco products:
IOS Software
IOS XE Software in autonomous mode
SD-WAN vBond Orchestrator Software
SD-WAN vEdge Routers
SD-WAN vManage Software
SD-WAN vSmart Controller Software
Workarounds
There are no workarounds that address these vulnerabilities.
Fixed Software
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.
Cisco IOS and IOS XE Software
To help customers determine their exposure to vulnerabilities in Cisco IOS and IOS XE Software, Cisco provides the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] to identify any Cisco Security Advisories that impact a specific software release and the earliest release that fixes the vulnerabilities described in each advisory (“First Fixed”). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories identified (“Combined First Fixed”).
Customers can use the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] to search advisories in the following ways:
Choose the software and one or more releases
Upload a .txt file that includes a list of specific releases
Enter the output of the show version command
After initiating a search, customers can customize the search to include all Cisco Security Advisories, a specific advisory, or all advisories in the most recent bundled publication.
Customers can also use the following form to determine whether a release is affected by any Cisco Security Advisory by entering a Cisco IOS or IOS XE Software release—for example, 15.1(4)M2 or 3.13.8S:
By default, the Cisco Software Checker ["https://sec.cloudapps.cisco.com/security/center/softwarechecker.x"] includes results only for vulnerabilities that have a Critical or High Security Impact Rating (SIR). To include results for Medium SIR vulnerabilities, customers can use the Cisco Software Checker on Cisco.com and check the Medium check box in the drop-down list under Impact Rating when customizing a search.
Standalone Cisco IOS XE SD-WAN Software
Cisco will not fix these vulnerabilities in standalone Cisco IOS XE SD-WAN Software releases. Customers who are running a standalone release must upgrade to a universal Cisco IOS XE Software release to address these vulnerabilities. The SD-WAN feature set was first integrated into the universal Cisco IOS XE Software releases starting with Cisco IOS XE Software Release 17.2.1r. For additional information, see the Install and Upgrade Cisco IOS XE Release 17.2.1r and Later ["https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/sdwan-xe-gs-book/install-upgrade-17-2-later.html"] chapter of the Cisco SD-WAN Getting Started Guide.
