CVE-2020-19767Public exploitNetwork attack vector

Token theft via unchecked self-destruct payout target

Published Sep 7, 2021 · Updated Aug 4, 2024

Token theft in the 0xRACER 1.0 smart contract allows attackers to redirect contract balances through a crafted calling contract. The destroycontract() function executes its self-destruct procedure with a caller-selected payout target and does not verify that target against the transaction address. An attacker must cause a victim contract to invoke the function; the resulting payout sends that contract balance to an attacker-controlled address.
