How to Fix GHSA-gwj5-wp6r-5q9f

To remediate this vulnerability, upgrade all affected Github.com/crypto org chain/cronos 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/crypto-org-chain/cronos fixed: 0.8.0 
Upgrade github.com/crypto-org-chain/cronos to 0.8.0
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/crypto-org-chain/cronos

How to Check if You Are Affected

To determine whether your application is affected by GHSA-gwj5-wp6r-5q9f, inspect your project dependencies for Github.com/crypto org chain/cronos:

inspect dependencies for github.com/crypto-org-chain/cronos

Analyze the terminal output to locate any version of Github.com/crypto org chain/cronos in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.8.0), 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-668: Exposure of Resource to Wrong Sphere, where the product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource. In Github.com/crypto org chain/cronos, 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

In Cronos nodes running versions before v0.7.0, the contract selfdestruct invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in Ethermint, all contracts that used the identical bytecode (i.e shared the same CodeHash) will also stop working once one contract invokes selfdestruct, even though the other contracts did not invoke the selfdestruct OPCODE. Thanks to the successfully coordinated security vulnerability disclosure, no smart contracts were impacted through the use of this vulnerability. Smart contract states and storage values are not affected by this vulnerability. This problem has been patched in Cronos v0.8.0. The patch has state machine-breaking changes and the required coordinated network upgrade was done on the block height 3982500 on the Cronos mainnet beta network. If a contract is subject to DoS due to this issue, the user can redeploy the same contract, i.e with identical bytecode, so that the original contract's code is recovered.
