Fund theft via unrestricted owner reassignment

Published Jan 19, 2024 · Updated Sep 3, 2024

Improper access control in UniswapFrontRunBot 0xdB94c allows remote attackers to take ownership and withdraw funds via Ethereum transactions. The setOwner function accepts calls from any address and replaces the owner without checking the caller, enabling the new owner to invoke withdrawal. Any network user able to submit an Ethereum transaction can drain the contract's Ether balance through this unrestricted ownership change.
