Strange exception found #1378

Closed pedrotbtl closed 3 years ago

pedrotbtl commented 4 years ago

Description

When I analyse the following contract, Mythril finds an assertion violation that does not seem to be correct. Is that correct?

RoomThermostat.sol is as follows.

pragma solidity >=0.4.25 <0.5.16;

contract RoomThermostat
{
    //Set of States
    enum StateType { Created, InUse}

    //List of properties
    StateType State;
    address Installer;
    address User;
    int TargetTemperature;
    enum ModeEnum {Off, Cool, Heat, Auto}
    ModeEnum  Mode;

    constructor(address thermostatInstaller, address thermostatUser) public
    {
        Installer = thermostatInstaller;
        User = thermostatUser;
        TargetTemperature = 70;

       assert(State == StateType.Created);
    }

    function StartThermostat() public
    {
        if (Installer != msg.sender || State != StateType.Created)
        {
            revert();
        }

       assert(State == StateType.Created);

        State = StateType.InUse;

       assert(State == StateType.InUse);
    }

    function SetTargetTemperature(int targetTemperature) public
    {
        if (User != msg.sender || State != StateType.InUse)
        {
            revert();
        }

       assert(State == StateType.InUse);

        TargetTemperature = targetTemperature;

       assert(State == StateType.InUse);
    }

    function SetMode(ModeEnum mode) public
    {
        if (User != msg.sender || State != StateType.InUse)
        {
            revert();
        }
       assert(State == StateType.InUse);

        Mode = mode;

       assert(State == StateType.InUse);
    }
}

How to Reproduce

I am using solc 0.5.10.

Run the following command: myth analyze --modules Exceptions RoomThermostat.sol

For example:

==== Exception State ====
SWC ID: 110
Severity: Medium
Contract: RoomThermostat
Function name: SetMode(uint8)
PC address: 895
Estimated Gas Usage: 3824 - 5239
An assertion violation was triggered.
It is possible to trigger an assertion violation. Note that Solidity assert() statements should only be used to check invariants. Review the transaction trace generated for this issue and either make sure your program logic is correct, or use require() instead of assert() if your goal is to constrain user inputs or enforce preconditions. Remember to validate inputs from both callers (for instance, via passed arguments) and callees (for instance, via return values).

Environment

Mythril version v0.22.4 solc 0.5.10

norhh commented 4 years ago

Its probably something to do with solc versions, can you try a different version. try using something like myth a file_name --solv 0.5.2

pedrotbtl commented 4 years ago

Thanks for the quick reply.

I tried running myth analyze --modules Exceptions RoomThermostat.sol with SOLC env variable pointed to solc 0.5.2 (https://github.com/ethereum/solidity/releases/download/v0.5.2/solc-static-linux) and mythril 0.22.1 now and mythril still finds this assertion violation.

norhh commented 4 years ago

can you try v0.22.4?

pedrotbtl commented 4 years ago

Just tried with v0.22.4 and solc 0.5.2 and still got the same output.

pedrotbtl commented 4 years ago

@norhh Are you able to reproduce this output? Is there some assumption/behaviour of Mythril that I am missing?

norhh commented 4 years ago

Using docker, now I am able to reproduce it 👍

pedrotbtl commented 4 years ago

Can you confirm whether this is a bug of Mythril or whether I am just missing some detail on how Mythril works?

norhh commented 4 years ago

For some reason I didn't get the exact error. Can you try it out with a docker container.Something like this docker run -v $(pwd):/home mythril/myth-dev a /home/thermo -m Exceptions --solv 0.5.1

Are you sure it's the same file as the one mentioned at the start of the post? As there is no assert at PC 960 for the mentioned file so it might be slightly different.

pedrotbtl commented 4 years ago

I copied the exact thing in the example and got the same error again. I am attaching here the file I used (had to rename .txt because github doesn't seem to allow .sol).

thermostat.txt

norhh commented 4 years ago

For some reason it still shows me the same output, Can you send me the output of disassembly. run myth d file.sol
