Gas Limit Issues/DoS with Block Gas Limit

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. Iterating through the users array without a limitation might cause the function to consume a lot of gas, especially when the array size is large. It may potentially reach the block gas limit and get...

Potential Gas Limit Issue with Bulk Score Updates

Lines of code Vulnerability details The updateScores function, which updates scores for multiple users, uses a nested loop structure. This can lead to a situation where if the users array is large and each user has many markets to update, the function could run out of gas. Impact If the function...

Hacking Gas Pumps via Bluetooth

Turns out pumps at gas stations are controlled via Bluetooth, and that the connections are insecure. No details in the article, but it seems that its easy to take control of the pump and have it dispense gas without requiring payment. Its a complicated crime to monetize, though. You need to sell...

No gas payment is done before calling the callContract in the Router.sol

Lines of code Vulnerability details Impact In the Axelar documentation it is specified that before calling callContract or callContractWithToken the user needs to first prepay the relayers gas fee on the source chain, but since the functions are not payable, nor does call...

The code uses assembly for memory allocation, which can be complex and prone to errors.

Lines of code Vulnerability details Impact The code uses assembly for memory allocation, which can be complex and prone to errors. Inefficient memory management can lead to gas inefficiency and potential vulnerabilities. Proof of Concept The code uses assembly for memory allocation, which can be...

Insufficient Gas Fee Estimation Leading to Incomplete Transactions

Lines of code Vulnerability details The contract allows a user to send Ether, presumably for transaction fees or gas. However, there is no mechanism in place to verify that the msg.value is sufficient to cover the actual gas cost for contract execution. Consequently, a scenario could arise where...

Potential Out-of-Bounds Error When Modifying Ranges

Lines of code Vulnerability details The method allows for the modification of a range based on an index. However, there's no explicit check to ensure that the provided indexToModify is within the bounds of the ranges array. If an out-of-bounds index is provided, the method will throw a generic...

Zero Amount Check Missing in reLP function

Lines of code Vulnerability details Impact If amount is 0, the reLP function will still execute all its operations, including external contract calls, which consume gas. This could lead to unnecessary gas costs for the caller. In a worst-case scenario, if this function is called repeatedly with...

Potential Over-redemption Vulnerability in redeem Function

Lines of code Vulnerability details Impact In the redeem function, when a third party is using their allowance to redeem shares on behalf of an owner, there exists a potential scenario where the third party could redeem more than originally intended by the owner. Proof of Concept This is how the...
