First, suppose that the owner adds the evil contract address to his sweepers. The evil contract looks like this: contract Exploit { uint public start; function sweep(address _token, uint _amount) returns (bool) { start = 0x123456789; return true;} }. Then, when one calls the function sweep() in the UserWallet contract, it will change the sweeperList to 0X123456789." } ] }, "problemtype" : { "problemtype_data" : [ { "description" : [ { "lang" : "eng", "value" : "n/a" } ] } ] }, "references" : { "reference_data" : [ { "name" : "https://github.com/hellowuzekai/blockchains/blob/master/delegatecall.md", "refsource" : "MISC", "url" : "https://github.com/hellowuzekai/blockchains/blob/master/delegatecall.md" } ] } }
