Fixed Software: Cisco considers any workarounds and mitigations (if applicable) to be temporary solutions until an upgrade to a fixed software release is available. To fully remediate these vulnerabilities and avoid future exposure as described in this advisory, Cisco strongly recommends that customers upgrade to the fixed software indicated in this advisory. Fixed Releases In the following table, the left column lists Cisco software releases. The right column indicates whether a release is affected by the vulnerabilities that are described in this advisory and the first release that includes the fix for these vulnerabilities. Customers are advised to upgrade to an appropriate fixed software release ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"] as indicated in this section. Cisco Catalyst SD-WAN Release First Fixed Release Earlier than 20.91 Migrate to a fixed release. 20.9 20.9.9.1 20.10 20.12.7.1 20.111 20.12.7.1 20.12 20.12.5.4 20.12.6.2 20.12.7.1 20.131 20.15.5.2 20.141 20.15.5.2 20.15 20.15.4.4 20.15.5.2 20.161 20.18.2.2 20.18 20.18.2.2 26.1 26.1.1.1 1. These releases have reached End of Software Maintenance ["https://www.cisco.com/c/en/us/products/routers/sd-wan/eos-eol-notice-listing.html"]. Cisco strongly encourages customers to upgrade to a supported release ["https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/compatibility-and-server-recommendations.html"]. The Cisco Product Security Incident Response Team (PSIRT) validates only the affected and fixed release information that is documented in this advisory. Cisco has also addressed this vulnerability in Cisco SD-WAN Cloud (Cisco Managed) Release 20.15.506, which is cloud based. No user action is required.

Recommendations: Cisco recommends upgrading the affected systems to a fixed software release. General Recommendations for Hardening Prevent access from unsecured networks, such as the internet, to the system. If internet access to the system is required, restrict system access to only known, trusted hosts on ports/protocols that are included in the user guides. Protect Cisco Catalyst SD-WAN Control Components behind a filtering device such as a firewall, and filter traffic to and from the systems while allowing only known, trusted hosts to send traffic to the systems. Using a two-layer firewall can provide flexibility in network planning so that end users do not connect directly to the outer DMZ. See the deployment sections of the Cisco Catalyst SD-WAN Design Guide ["https://www.cisco.com/c/en/us/td/docs/solutions/CVD/SDWAN/cisco-sdwan-design-guide.html#DeploymentPlanning"]. Regularly monitor log traffic for any unexpected traffic to and from systems. Logging should be sent to an external server, if possible, and kept for a long enough duration so that post-event investigations can be performed with sufficient log data. Disable HTTP for the Cisco Catalyst SD-WAN Manager web UI administrator portal. Disable any network services that are not required, including HTTP and FTP. For more information about specific service functionality, see the Cisco Catalyst SD-WAN user guides. Upgrade the system to the latest version of Cisco Catalyst SD-WAN Software. Change the default administrator password to a more secure variant. Restrict access to the administrator account by creating user accounts based on necessary access requirements. In addition, create operator accounts for all administrators. Use SSL/TLS, obtain an SSL certificate from a certificate authority (CA), or create a self-signed certificate. For more information, review the Cisco Catalyst SD-WAN Hardening Guide ["https://sec.cloudapps.cisco.com/security/center/resources/Cisco-Catalyst-SD-WAN-HardeningGuide"].

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
