CVE-2018-13144
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 transfer and transferFrom functions of a smart contract implementation for Pandora (PDX), an Ethereum token, have an integer overflow. NOTE: this has been disputed by a third party.
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 transfer() and transferFrom() functions of the Pandora (PDX) Ethereum token smart contract. The vulnerability allows arithmetic operations on token balances to exceed maximum integer limits, potentially enabling attackers to manipulate transfer amounts or balances. This is a classic Solidity vulnerability common in contracts using Solidity versions prior to 0.8 that lack built-in overflow protection.

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.
-
Confirm PDX token holdings or interactionCheck your Ethereum wallet, exchange account, or smart contract interaction history for Pandora (PDX) token balances or transactionsAffected if You hold PDX tokens or have interacted with the Pandora token contract on any Ethereum-compatible blockchain
-
Identify the PDX contract addressLocate the contract address used for your PDX tokens - check Etherscan or your wallet's token transfer records for the 'to' address in PDX transactionsAffected if You are using a contract address that corresponds to the vulnerable Pandora token deployment
-
Retrieve the contract source codeOn Etherscan (or similar block explorer), go to the Contract tab for the PDX token address and look for verified source code. If source is not verified, the contract bytecode will be availableAffected if The contract source code is available and shows Solidity version prior to 0.8 without SafeMath library imported
-
Check Solidity compiler versionIn the contract source code metadata or verified source tab, locate the 'pragma solidity' declaration at the top of the contract fileAffected if The contract declares a Solidity version below 0.8 (e.g., pragma solidity ^0.4.0 or ^0.6.0)
-
Verify overflow protection in transfer functionsLocate the transfer() and transferFrom() function definitions in the contract source code. Check whether they use SafeMath methods (like safeAdd, safeSub, safeMul) or direct arithmetic operators (+, -, *)Affected if The transfer or transferFrom functions use direct arithmetic (balance[from] + amount, etc.) without SafeMath library calls or Solidity 0.8+ overflow checks
You are affected if you hold or interact with Pandora (PDX) tokens deployed from a Solidity version below 0.8 where the transfer() and transferFrom() functions perform arithmetic without SafeMath or built-in overflow protection.

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 dataDeploy a patched contract version using SafeMath library (Solidity < 0.8) or compiled with Solidity 0.8+ (which includes built-in overflow checks). Coordinate token migration for existing holders to the new secure contract. NOTE: Third party dispute may warrant independent verification of the vulnerability claim.
