CVSS: 7.1EPSS: 0%CPEs: 2EXPL: 1CVE-2023-46132 – Crosslinking transaction attack in hyperledger/fabric
https://notcve.org/view.php?id=CVE-2023-46132
Hyperledger Fabric is an open source permissioned distributed ledger framework. Combining two molecules to one another, called "cross-linking" results in a molecule with a chemical formula that is composed of all atoms of the original two molecules. In Fabric, one can take a block of transactions and cross-link the transactions in a way that alters the way the peers parse the transactions. If a first peer receives a block B and a second peer receives a block identical to B but with the transactions being cross-linked, the second peer will parse transactions in a different way and thus its world state will deviate from the first peer. Orderers or peers cannot detect that a block has its transactions cross-linked, because there is a vulnerability in the way Fabric hashes the transactions of blocks. • https://github.com/hyperledger/fabric/security/advisories/GHSA-v9w2-543f-h69m • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Hyperledger Fabric 2.3 allows attackers to cause a denial of service (orderer crash) by repeatedly sending a crafted channel tx with the same Channel name. NOTE: the official Fabric with Raft prevents exploitation via a locking mechanism and a check for names that already exist. Hyperledger Fabric 2.3 permite a los atacantes provocar una denegación de servicio (caída del pedido) enviando repetidamente un tx de canal diseñado con el mismo nombre de canal. NOTA: el Fabric with Raft oficial evita la explotación mediante un mecanismo de bloqueo y una verificación de nombres que ya existen. • https://github.com/SmartBFT-Go/fabric/issues/286 https://github.com/hyperledger/fabric/pull/2934 • CWE-670: Always-Incorrect Control Flow Implementation •

https://notcve.org/view.php?id=CVE-2022-36023
Hyperledger Fabric is an enterprise-grade permissioned distributed ledger framework for developing solutions and applications. If a gateway client application sends a malformed request to a gateway peer it may crash the peer node. Version 2.4.6 checks for the malformed gateway request and returns an error to the gateway client. There are no known workarounds, users must upgrade to version 2.4.6.

https://notcve.org/view.php?id=CVE-2022-31121
Hyperledger Fabric is a permissioned distributed ledger framework. In affected versions if a consensus client sends a malformed consensus request to an orderer it may crash the orderer node. A fix has been added in commit 0f1835949 which checks for missing consensus messages and returns an error to the consensus client should the message be missing. Users are advised to upgrade to versions 2.2.7 or v2.4.5. There are no known workarounds for this issue. • https://github.com/hyperledger/fabric/commit/0f18359493bcbd5f9f9d1a9b05adabfe5da23b06 https://github.com/hyperledger/fabric/releases/tag/v2.2.7 https://github.com/hyperledger/fabric/releases/tag/v2.4.5 https://github.com/hyperledger/fabric/security/advisories/GHSA-72x4-cq6r-jp4p • CWE-20: Improper Input Validation •
