How to Fix CVE-2023-33964

To remediate this vulnerability, upgrade all affected Github.com/multiversx/mx chain go 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/multiversx/mx-chain-go fixed: 1.4.16 
Upgrade github.com/multiversx/mx-chain-go to 1.4.16
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/multiversx/mx-chain-go

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-33964, inspect your project dependencies for Github.com/multiversx/mx chain go:

inspect dependencies for github.com/multiversx/mx-chain-go

Analyze the terminal output to locate any version of Github.com/multiversx/mx chain go in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.16), 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/multiversx/mx chain go, 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 Metachain cannot process a cross-shard miniblock. An invalid transaction with the wrong username on metachain is not treated correctly on the metachain transaction processor. This is strictly a processing issue that could have happened on MultiversX chain. If an error like this had occurred, the metachain would have stopped notarizing blocks from the shard chains. The resuming of notarization is possible only after applying a patched binary version. ### Patches Introduce processIfTxErrorCrossShard for metachain transaction processor. ### Workarounds No ### References No
