概要

JGroups before 4.0 does not require the proper headers for the ENCRYPT and AUTH protocols from nodes joining the cluster, which allows remote attackers to bypass security restrictions and send and receive messages within the cluster via unspecified vectors. Fixes for this issue have been backported to versions 3.6.10.Final and 3.2.16.Final.

NVD の説明

It was found that JGroups did not require necessary headers for encrypt and auth protocols from new nodes joining the cluster. An attacker could use this flaw to bypass security restrictions, and use this vulnerability to send and receive messages within the cluster, leading to information disclosure, message spoofing, or further possible attacks.
