Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Hyperledger Fabric version 2.3

Description The issue allows attackers to cause a denial of service by repeatedly sending a crafted channel transaction with the same channel name, leading to an orderer crash. However, the official Fabric with Raft prevents exploitation through a locking mechanism and a check for existing names.

Recommendations For Hyperledger Fabric version 2.3, consider implementing a locking mechanism and a check for existing channel names to prevent the denial of service attack, similar to the official Fabric with Raft.
