In part two of our oil and gas series, we look at more threats that can expose the industry to cyberattacks...

Oil and Gas Cybersecurity: Industry Overview Part 1

With geopolitical tensions running high, oil and gas companies may be more susceptible to cyberattacks...

Malicious manipulation of gas reserve can deny access to MIMOProxy

Lines of code Vulnerability details The MIMOProxy contract defines a minGasReserve value as a storage variable: MIMOProxy.solL18: /// @inheritdoc IMIMOProxy uint256 public override minGasReserve; The execute function uses this minGasReserve value to calculate a gas stipend to provide to the targe...

QA Report

Prevent possible future storage collisions The target action contracts of MIMOProxy.sol use storage slot 0 for immutable addresses, which doesn't currently pose an issue; however, if in future additional contracts are added which allow this slot in storage to be modified then it could open the...

Calculating project cost is vulnerable to reaching block gas-limit

Lines of code Vulnerability details Impact The function Project.projectCost calculates the project costs by calculating the sum of all project task costs. However, due to the unbound for loop, iterating over a potentially large amount of project tasks, this function can potentially DoS due to...

projectCost may be reverted due to out of gas problem if having too many tasks. lendToProject and recoverTokens may always revert because of this.

Lines of code Vulnerability details Impact projectCost may be reverted due to out of gas problem if having too many tasks. lendToProject and recoverTokens may always revert because of this. If lendToProject always revert, community owner won't be able to lends fund to the published project. Tasks...

Possible DOS in lendToProject() and toggleLendingNeeded() function because unbounded loop can run out of gas

Lines of code Vulnerability details Impact In Project contract, the lendToProject function might not be available to be called if there are a lot of Task in tasks list of project. It means that the project cannot be funded by either builder or community owner. This can happen because lendToProjec...

Add cancel and refund option for Transaction Recovery

Lines of code Vulnerability details Add cancel and refund option for Transaction Recovery Impact Transactions could fail or stuck, according to the documentation: Occasionally, transactions can get "stuck" in the pipeline from a source to destination chain e.g. due to one-off issues that arise wi...

Unable To Verify Signature If There Are Too Many Signers And Operators

Lines of code Vulnerability details It was observed that there is a nested for loop within the AxelarAuthWeighted.validateSignatures function. If there are a large number of signatures and operators, it will result in an "Out of Gas" error or a "Block Gas Limit" error and the command's signature...

Potential scenario where an attacker can steal a user's gas refund

Lines of code Vulnerability details Impact Anybody is allowed to add gas for a specific tx. I was trying to figure out whether the following scenarios are possible: 1. Alice sends a public tx where she deposits some gas and calls the gateway contract after 2. Bob, the attacker, catches that...

CVE-2022-35915

OpenZeppelin Contracts is a library for secure smart contract development. The target contract of an EIP-165 supportsInterface query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a bounded cost. The issue has been fixed in...

CVE-2022-35915

OpenZeppelin Contracts contains a vulnerability in the ERC165 supportsInterface logic where querying a target contract can cause unbounded gas consumption by returning a large amount of data. The issue is fixed in version 4.7.2; users are advised to upgrade. There are no public workarounds noted....

Name of the Vulnerable Software and Affected Versions: OpenZeppelin Contracts versions prior to 4.7.2 Description: The target contract of an EIP-165 supportsInterface query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a...

Upgraded Q -> M from 264 [1659038303960]

Judge has assessed an item in Issue 264 as Medium risk. The relevant finding follows: L-05 Unbounded loop on array can lead to DoS As these arrays can grow quite large only push operations, no pop, the transaction's gas cost could exceed the block gas limit and make it impossible to call the...

gas-vermittlung.de Cross Site Scripting vulnerability OBB-2803051

Following the coordinated and responsible vulnerability disclosure guidelines of the ISO 29147 standard, Open Bug Bounty has: a. verified the vulnerability and confirmed its existence; b. notified the website operator about its existence. Technical details of the vulnerability are currently hidde...

call() should be used instead of transfer() on an address payable

Lines of code Vulnerability details Impact The use of the deprecated transfer function for an address will inevitably make the transaction fail when the caller is a smart contract and: 1. Does not implement a payable function. 2. Implements a payable fallback which uses more than 2300 gas unit. 3...
