How to Fix CVE-2022-36023

To remediate this vulnerability, upgrade all affected Github.com/hyperledger/fabric dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/hyperledger/fabric fixed: 2.4.6

Upgrade github.com/hyperledger/fabric to 2.4.6

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for github.com/hyperledger/fabric

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-36023, inspect your project dependencies for Github.com/hyperledger/fabric:

inspect dependencies for github.com/hyperledger/fabric

Analyze the terminal output to locate any version of Github.com/hyperledger/fabric in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.6), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Github.com/hyperledger/fabric, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact If a gateway client application sends a malformed request to a gateway peer it may crash the peer node. This fix checks for the malformed gateway request and returns an error to the gateway client. ### Patches Fixed in v2.4.6. ### Workarounds None, users must upgrade to v2.4.6. ### References https://github.com/hyperledger/fabric/releases/tag/v2.4.6 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Fabric](https://github.com/hyperledger/fabric) ### Credits Thank you to Haosheng Wang of OPPO ZIWU Security Lab for this disclosure.
