CVE-2018-18425 : What You Need to Know

Primeo (PEO) smart contract implementation on Ethereum has a vulnerability in the doAirdrop function, allowing the contract owner to issue currency without proper verification, potentially devaluing the token.

Understanding CVE-2018-18425

The vulnerability in the doAirdrop function of the Primeo (PEO) smart contract allows the contract owner to bypass the hard cap specified in the contract, leading to potential token devaluation.

What is CVE-2018-18425?

The flaw in the doAirdrop function enables the contract owner to issue any amount of currency without verifying the numerical relationship between the airdrop amount and the token's total supply, undermining the token's hard cap and diminishing its value.

The Impact of CVE-2018-18425

This vulnerability poses a significant risk as it allows unauthorized issuance of currency, potentially leading to a devaluation of the token and undermining the integrity of the smart contract.

Technical Details of CVE-2018-18425

The technical aspects of the CVE-2018-18425 vulnerability provide insight into the affected systems and the exploitation mechanism.

Vulnerability Description

The doAirdrop function in the Primeo (PEO) smart contract fails to validate the relationship between the airdrop amount and the token's total supply, enabling the contract owner to issue currency without adhering to the hard cap restrictions.

Affected Systems and Versions

Product: Not applicable
Vendor: Not applicable
Versions: Not applicable

Exploitation Mechanism

The vulnerability allows the contract owner to manipulate the total supply of the token by issuing arbitrary amounts of currency through the doAirdrop function, disregarding the hard cap constraints specified in the contract.

Mitigation and Prevention

Addressing CVE-2018-18425 requires immediate steps to mitigate the risk and ensure long-term security practices.

Immediate Steps to Take

Disable the doAirdrop function or implement proper validation checks to ensure the relationship between airdrop amounts and total supply.
Monitor the smart contract for any unauthorized currency issuances.

Long-Term Security Practices

Conduct regular security audits and code reviews to identify and address vulnerabilities promptly.
Educate developers on secure coding practices to prevent similar issues in future smart contract implementations.

Patching and Updates

Apply patches or updates provided by the smart contract developer to fix the vulnerability and enhance the security of the Primeo (PEO) token smart contract.
