What is CVE-2022-20860?

CVE-2022-20860 is a high-severity vulnerability in Cisco Nexus Dashboard, published on 21 Jul 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

A vulnerability in the SSL/TLS implementation of Cisco Nexus Dashboard could allow an unauthenticated, remote attacker to alter communications with associated controllers or view sensitive information. This vulnerability exists because SSL server certificates are not validated when Cisco Nexus Dashboard is establishing a connection to Cisco Application Policy Infrastructure Controller (APIC), Cisco Cloud APIC, or Cisco Nexus Dashboard Fabric Controller, formerly Data Center Network Manager (DCNM) controllers. An attacker could exploit this vulnerability by using man-in-the-middle techniques to intercept the traffic between the affected device and the controllers, and then using a crafted certificate to impersonate the controllers. A successful exploit could allow the attacker to alter communications between devices or view sensitive information, including Administrator credentials for these controllers.
