CVE-2018-13611
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 CDcurrency, 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 · high confidenceThe mintToken function in the CDcurrency Ethereum smart contract contains an integer overflow vulnerability that permits the contract owner to manipulate any user's token balance to an arbitrary value.

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.
-
Locate the CDcurrency smart contract deploymentIdentify the blockchain network (Ethereum mainnet or testnet) and the contract address where Ucoincorp Cdcurrency is deployedAffected if The contract is deployed at a known address on any network
-
Retrieve the contract source codeObtain the deployed contract source code from Etherscan or other block explorer, or decompile the bytecode if source is unavailableAffected if Source code cannot be verified and the contract appears to handle token balances
-
Inspect the mintToken functionSearch the source code for the mintToken function and examine its implementation for integer arithmetic operations on token balancesAffected if The mintToken function performs arithmetic (addition, multiplication) on balance variables without SafeMath or explicit overflow checks
-
Check for SafeMath library usageSearch the contract code for 'using SafeMath' statements or imported SafeMath library references in balance-modifying functionsAffected if No SafeMath library is imported or used for arithmetic operations on token balances
-
Verify overflow vulnerabilityExamine whether the mintToken function allows the contract owner to set arbitrary balances by adding to existing balances without bounds checkingAffected if The function permits unrestricted balance modification without validated overflow checks
The environment is affected if the CDcurrency smart contract is deployed and its mintToken function lacks SafeMath or explicit overflow/underflow checks in balance arithmetic operations.

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 dataReplace integer arithmetic with SafeMath library functions or implement explicit overflow/underflow checks in the mintToken function, and conduct a broader security audit for similar vulnerabilities.
