Description
AST-01: Hardcoded Ethereum Addresses with Placeholder Private Keys in Demo
Severity: MEDIUM
Affected File(s): demo/aster-code.py:16-23
Description
Demo script contains hardcoded Ethereum wallet addresses with private keys set to '*'. The addresses are valid checksummed Ethereum addresses. Users copying this pattern will likely hardcode their own private keys in source files.
Vulnerable Code
user = '0x014c85ffb0fF2F2972237AA950B452f92C69Ae1D'
main_private_key = '*'
signer = '0xC98Fd64eBc39E28b92849d9cCef9495663439014'
priKey = '*'
Impact
Users will copy this template and paste real private keys into source code, leading to leakage through version control. Hardcoded IP addresses may identify internal infrastructure.
Recommended Fix
Load all credentials from environment variables in demo code. Use clearly fake addresses. Add warning comment about never committing private keys.
