How to Fix GHSA-hg58-rf2h-6rr7

To remediate this vulnerability, upgrade all affected Github.com/cometbft/cometbft 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/cometbft/cometbft fixed: 0.37.7 
Upgrade github.com/cometbft/cometbft to 0.37.7
github.com/cometbft/cometbft fixed: 0.38.8 
Upgrade github.com/cometbft/cometbft to 0.38.8
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/cometbft/cometbft

How to Check if You Are Affected

To determine whether your application is affected by GHSA-hg58-rf2h-6rr7, inspect your project dependencies for Github.com/cometbft/cometbft:

inspect dependencies for github.com/cometbft/cometbft

Analyze the terminal output to locate any version of Github.com/cometbft/cometbft in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.37.7), 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-610: Externally Controlled Reference to a Resource in Another Sphere, where the product uses an externally controlled name or reference that resolves to a resource that is outside of the intended control sphere. In Github.com/cometbft/cometbft, 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

**Name**: ASA-2024-008: Instability during blocksync when syncing from malicious peer **Component**: CometBFT **Criticality**: Medium ([ACMv1](https://github.com/interchainio/security/blob/main/resources/CLASSIFICATION_MATRIX.md): I:Moderate; L: Possible) **Affected versions**: < v0.38.7 # Summary An issue was identified for nodes syncing on an existing network during blocksync in which a malicious peer could cause the syncing peer to panic, enter into a catastrophic invalid syncing state or get stuck in blocksync mode, never switching to consensus. It is recommended for all clients to adopt this patch so that blocksync functions as expected and is tolerant of malicious peers presenting invalid data in this situation. Nodes that are vulnerable to this state may experience a Denial of Service condition in which syncing will not work as expected when joining a network as a client. # Recognition This issue was reported to the Cosmos Bug Bounty Program on HackerOne on 5/01/24 by unknown_feature.
