Summary

Lack of Input Validation Vulnerability in ProxyFactory Contract

Vulnerability Details

The vulnerability arises from the lack of input validation in various functions of the ProxyFactory contract. For example, functions like setContest and deployProxyAndDistribute do not explicitly validate the input parameters, which could lead to unintended behavior or manipulation of contest settings.

Impact

Without proper input validation, unauthorized actors could manipulate contest details, deploy proxy contracts with unintended parameters, or exploit other contract functions in unintended ways.

Tools Used

Manual code review and analysis of input validation in the ProxyFactory contract.

Recommendations

To mitigate this vulnerability, consider the following recommendations:

1. Input Validation: Implement thorough input validation checks in functions that take user-defined parameters. Verify the correctness and validity of input data before proceeding with contract operations.

2. Access Control: Implement access control mechanisms to ensure that only authorized users can call sensitive functions that can modify contract state.

3. Sanitize Data: Ensure that user-provided data is sanitized and verified before using it in contract operations to prevent potential manipulation or attacks.
