CVE-2020-9040
Couchbase Server Java SDK before 2.7.1.1 allows a potential attacker to forge an SSL certificate and pose as the intended peer.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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 SDK's Netty component due to missing hostname verification.
