Wrong dependency configuration, leading to EmergencyMigration to fail

wetzo

Summary

Dependency configuration in Laundrette.sol::configureDependencies is not properly set, with index 0 overwritten.

Vulnerability Details

The index 0 of dependencies is first set to toKeycode("MONEY") but then immediately overridden by toKeycode("WEAPN") by mistake. This prevents the address of moneyShelf to change to moneyVault in case of EmergencyMigration.

Impact

The return value of Laundrette.sol::configureDependencies will be unexpected. In case of EmergencyMigration, the dependencies will not be updated as intended and the deposit and withdraw functions will not be restricted, potentially leading to fund loses as the protocol will not be frozen.

Recommendations

- dependencies[0] = toKeycode("WEAPN");
+ dependencies[1] = toKeycode("WEAPN");
