How to Fix CVE-2022-35253

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-2022-35253, 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-400: Uncontrolled Resource Consumption, where the product does not properly control the allocation and maintenance of a limited resource. 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

A vulnerability exists in Hyperledger Fabric < 2.4 could allow an attacker to construct a non-validated request that could cause a denial of service attack. The peer gateway service tries to extract channel and chaincode information from the signed proposal, but it doesn't check the proposal fields for validity. Therefore a malformed proposal might end up crashing the peer service. This issue has been patched in 2.4.6. There are no known workarounds.
