CVE-2018-13606
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe mintToken function of a smart contract implementation for ARChain, an Ethereum token, has an integer overflow that allows the owner of the contract to set the balance of an arbitrary user to any value.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInteger overflow vulnerability in the mintToken function of the ARChain Ethereum token smart contract allows the contract owner to manipulate arbitrary user balances to any value through overflow exploitation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ARChain token contract deploymentSearch your deployed smart contracts for any instance matching the Archain token contract address or name. Check your contract registry or blockchain explorer for contracts named 'ARChain' or 'Archain'.Affected if You have deployed or actively interact with the ARChain token smart contract on any network.
-
Locate the mintToken function sourceObtain the deployed contract source code from a blockchain explorer, your codebase, or the Archain project repository. Search for a function named 'mintToken' within the contract.Affected if The contract source contains a function called 'mintToken' that handles token minting.
-
Inspect mintToken for SafeMath usageExamine the mintToken function code. Look specifically at arithmetic operations involving token amounts and balances. Check whether the code imports and uses the SafeMath library for addition operations on balances.Affected if The mintToken function performs arithmetic on balances without SafeMath library (or equivalent overflow protection), allowing integer overflow.
-
Verify balance manipulation vulnerabilityReview the mintToken function logic to confirm it allows the contract owner to directly modify user balance variables without proper bounds checking. Specifically look for patterns where balance[user] = balance[user] + amount could overflow.Affected if The function permits the owner to add any amount to user balances through direct arithmetic assignment without overflow safeguards.
You are affected if you have deployed or interact with the ARChain token contract and its mintToken function lacks SafeMath protection against integer overflow.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataFix requires using SafeMath library for arithmetic operations to prevent integer overflows, plus implementing proper access controls and validation on the mintToken function.
