The Vulnerabilities Addressed

The patches addressed numerous critical vulnerabilities and exposures (CVEs), including serious threats such as command injections, SQL injections, DLL hijacking, cross-site request forgery attacks, directory traversals, and more. Some of the most critical, such as a buffer overflow in SD-Wan, allow for unauthenticated, remote code execution as the root user and should be patched immediately. Cisco does not believe these were actively being used in the wild, but they should nonetheless be treated seriously and patched immediately. 

Remediation

Cisco recommends patching all affected products as soon as possible as there are no current workarounds to the newly released critical vulnerabilities. A full list of Cisco’s recent security advisories is also available from the company’s security center.
