GHSA-4j93-fm92-rp4m: ASA-2024-003: Missing `BlockedAddressed` Validation in Vesting Module
ASA-2024-003: Missing <code>BlockedAddressed</code> Validation in Vesting Module
Component: Cosmos SDK Criticality: Low Affected Versions: Cosmos SDK versions <= 0.50.3; <= 0.47.8 Affected Users: Chain developers, Validator and Node operators Impact: Denial of Service
Description
A vulnerability was identified in the x/auth/vesting
module, which can allow a user to create a periodic vesting account on a blocked address, for example a non-initialized module account. Additional validation was added to prevent creation of a periodic vesting account in this scenario.
If this case is triggered, there is the potential for a chain halt if the uninitialized account in question is called by GetModuleAccount
in Begin
/EndBlock
of a module. This combination of an uninitialized blocked module account is not common.
Next Steps for Impacted Parties
If your chain has uninitialized blocked module accounts, it is recommended to proactively initialize them, as they are often initialized during a chain migration or during init genesis.
If 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.
A Github Security Advisory for this issue is available in the Cosmos-SDK repository. For more information about Cosmos SDK, see https://docs.cosmos.network/.
