Couchbase Server Java SDK before 2.7.1.1 allows a potential attacker to forge an SSL certificate and pose as the intended peer. An attacker can leverage this flaw by crafting a cryptographically valid certificate that will be accepted by Java SDKs Netty component due to missing hostname verification.

Weakness

The product does not validate, or incorrectly validates, a certificate.
