GHSA-86h5-xcpx-cfqc: ASA-2024-005 Potential Slashing Evasion During Re-delegation Vulnerability
LOWGHSA-86h5-xcpx-cfqc is a LOW potential slashing evasion during re-delegation vulnerability (CWE-372: Incomplete Internal State Distinction) affecting ASA-2024-005 libraries in the Go ecosystem. The issue involves potential slashing evasion during re-delegation. Remediation is available by upgrading affected packages to version 0.50.5, 0.47.10.
GHSA-86h5-xcpx-cfqc at a Glance
How to Fix GHSA-86h5-xcpx-cfqc
To remediate this vulnerability, upgrade all affected ASA-2024-005 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade github.com/cosmos/cosmos-sdk to 0.50.5Upgrade github.com/cosmos/cosmos-sdk to 0.47.10Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for github.com/cosmos/cosmos-sdkHow to Check if You Are Affected
To determine whether your application is affected by GHSA-86h5-xcpx-cfqc, inspect your project dependencies for ASA-2024-005:
inspect dependencies for github.com/cosmos/cosmos-sdkAnalyze the terminal output to locate any version of ASA-2024-005 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.50.5), 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-372: Incomplete Internal State Distinction, where the product does not properly determine which state it is in, causing it to assume it is in state x when in fact it is in state y, causing it to perform incorrect operations in a security-relevant manner. In ASA-2024-005, 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.

"details" : "## ASA-2024-005: Potential slashing evasion during re-delegation\n\n**Component**: Cosmos SDK\n**Criticality**: Low\n**Affected Versions**: Cosmos SDK versions <= 0.50.4; <= 0.47.9\n**Affected Users**: Chain developers, Validator and Node operators\n**Impact**: Slashing Evasion\n\n## Summary\n\nAn issue was identified in the slashing mechanism that may allow for the evasion of slashing penalties during a slashing event. If a delegation contributed to byzantine behavior of a validator, and the validator has not yet been slashed, it may be possible for that delegation to evade a pending slashing penalty through re-delegation behavior. Additional validation logic was added to restrict this behavior.\n\n## Next Steps for Impacted Parties\n\nIf you are a chain developer on an affected version of the Cosmos SDK, it is advised to update to the latest available version of the Cosmos SDK for your project. Once a patched version is available, it is recommended that network operators upgrade.\n\nA Github Security Advisory for this issue is available in the Cosmos-SDK [repository](https://github.com/cosmos/cosmos-sdk/security/advisories/GHSA-86h5-xcpx-cfqc). For more information about Cosmos SDK, see https://docs.cosmos.network/.\n\nThis issue was found by cat shark (Khanh) who reported it to the Cosmos Bug Bounty Program on HackerOne on December 6, 2023.
