Lack of access control to Controller from another devs deployed contract
Days in Operation:
UvToken is the native token for UvTokenWallet, or a User-Friendly Multi-Chain Wallet. Beosin reported that the UvTokenWallet's Eco Staking project has been hacked for $1.5m, or 5,011 BNB.
Beosin reported that the attacker uses the 0xc81daf6e method with Controller privileges of another contract deployed by the devs, which calls the 0x7e39d2f8 method of the victim contract. As the contract has Controller privileges, it directly transfers all the UVT tokens through verification. Stolen funds were deposited into Tornado.Cash.
