7.4 highCVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:NCVE-2019-9764
High (7.4) in hashicorp consul. EPSS 0.6% chance of exploitation in the next 30 days. Fixed in github.com/hashicorp/consul 1.4.4.
HashiCorp Consul 1.4.3 lacks server hostname verification for agent-to-agent TLS communication. In other words, the product behaves as if verify_server_hostname were set to false, even when it is actually set to true. This is fixed in 1.4.4.
